Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 6/19/2026 has been entered.
Response to Arguments
(A) Applicant’s arguments, see pages 4-5, filed “ on “Claim 1 is rejected for having been amended to include new matter, specifically the claim feature: "wherein the notification means provides notification of the arrival of the maintenance time in the same manner on both the home screen and the screen on which the reset setting means is provided." However, paragraphs [0041]-[0046] of the specification as well as alarm notation column 13b in Figs. 2 (home screen) and 5 (screen on which the reset setting means is provided) provide support for the claim feature”, with respect to claim rejections under 35 USC § 112 have been fully considered and are persuasive.
As to point (A), the claim rejections under 35 USC § 112 Claims 1-7 has been withdrawn.
(B) Applicant's arguments filed “Example 42 ("Method for Transmission of Notifications When Medical Records Are Updated") in the 2019 PEG regarding Subject Matter Eligibility which, although determined to be directed to an abstract idea, integrates the abstract idea into a practical application. Claim 1 of the claimed invention is analogous to that of claim 1 of Example 42. Claim 1 of Example 42 recites a method comprising storing information, providing remote access over a network, converting non-standardized updated information into the standardized format, storing the standardized updated information, automatically generating a message containing the updated information, and then transmitting the message to all of the users over the computer network. The 2019 PEG determines that the claim recites an abstract idea, but that it also "integrates the method of organizing human activity into a practical application" because "the additional elements recite a specific improvement over prior art systems by allowing remote users to share information in real time in a standardized format regardless of the format in which the information was input by the user"'” and “the claimed invention comprises a storage means that stores a cumulative time of use, a display device that shows a home screen that includes displaying consumables, a notification means, a plurality of setting means, and a selection means, a notification means that provides a notification of arrival of a maintenance time, etc. Even if the claim recited the alleged abstract idea, it integrates the abstract idea into a practical application because the additional elements recite a specific improvement over prior art systems through storing a cumulative time of use of consumables and converting this into a notification of arrival of a maintenance time based on this cumulative time of the consumables on both the home screen and the screen on which the reset setting means is provided.” on 6/19/2026 have been fully considered but they are not persuasive.
As to point (B), upon further consideration, The examiner further notes displaying a home screen, providing notifications of maintenance time, and resetting the maintenance time based on selection does not indicate any improvement of the existing prior art. The process is well known to a person having ordinary skill in the art. Furthermore, Example 42 included a process of converting updated information that was input by a user in a non-standardized form to a standardized format which integrates the method of organizing human activity into a practical application. The claims are not similar as the claim limitations does not include any form of transformation of data.
(C) Applicant’s arguments, see pages 6-8, filed “neither Kudou nor Gronsbell teach storing a cumulative time of the consumables including engine oil, an engine oil filter, hydraulic oil, a hydraulic oil return filter, and a hydraulic oil filter that require maintenance depending on use, only, according to Gronsbell's paragraph [0111], fuel information and battery information. Therefore, a person of ordinary skill in the art would not have found the claimed invention obvious over the cited prior art, Kudou in view of Gronsbell. Claims 2-7 are dependent on claim 1, and therefore also would not have been found obvious by a person of ordinary skill in the art for at least the same reason as claim 1. Withdrawal of the rejection is respectfully requested” on 6/19/2026, with respect to the rejection(s) of claim(s) 1-7 under 35 USC § 103 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn.
As to point (C), upon further consideration, a new ground(s) of rejection is made in view of KINUGAWA (JP2012211478A).
Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claims 1-7 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more.
101 Analysis-Step 1
Claims 1-6 are directed to A display device of a work machine (i.e., a machine). Therefore, claims 1-6 are within at least one of the four statutory categories.
101 Analysis-Step 2A, Prong I
Regarding Prong I of the Step 2A analysis in the 2019 PEG, the claims are to be analyzed to determine whether they recite subject matter that falls within one of the follow groups of abstract ideas: a) mathematical concepts, b) certain methods of organizing human activity, and/or c) mental processes.
Independent claim 1 includes limitations that recite an abstract idea (emphasized below) and will be used as a representative claim for reminder of the 101 rejection. Claim 1 recites:
A display device of a work machine, comprising:
a storage means that stores a cumulative time of use with respect to consumables of the work machine, the consumables including engine oil, an engine oil filter, hydraulic oil, a hydraulic oil return filter, and a hydraulic oil filter that require maintenance depending on use;
the display device that shows a home screen, which includes at least one of the consumables; a notification means; a plurality of function setting means; and a selection means;
the notification means that provides a notification of arrival of a maintenance time of the consumable on the basis of the cumulative time;
the plurality of function setting means for respectively setting in the display device a plurality of functions of the work machine; and
the selection means for selecting any of the plurality of function setting means in the display device, wherein the plurality of function setting means has a reset setting means for resetting the cumulative time, and
the selection means performs visual recognition display that allows visual recognition of a procedure leading to the reset setting means regarding at least one of the consumable for which the maintenance time has arrived,
wherein the notification means provides notification of the arrival of the maintenance time, and the visual recognition display is also performed, on the home screen displayed on the display device wherein the display device allows transition from the home screen to a screen on which the reset setting means is provided,
wherein the notification means provides notification of the arrival of the maintenance time in the same manner on both the home screen and the screen on which the reset setting means is provided.
The examiner submits that the foregoing bolded limitation(s) constitute a "mental process" and/or “certain methods of organizing human activity” because under its broadest reasonable interpretation, the claim covers performance of the limitation by a user or in the human mind. For example, “the plurality of function setting means for respectively setting … a plurality of functions of the work machine” in the context of this claim encompasses the user mental selections indicating which data to memorize. Similarly, the limitation of "the selection means for selecting any of the plurality of function setting means… , wherein the plurality of function setting means has a reset setting means for resetting the cumulative time" in the context of this claim encompasses the user mental selection to clearing the memorized data. Accordingly, the claim recites at least one abstract idea.
101 Analysis-Step 2A, Prong II
Regarding Prong II of the Step 2A analysis in the 2019 PEG, the claims are to be analyzed to determine whether the claim as a whole, integrates the abstract into a partial application. As noted in the 2019 PEG, it must be determined whether there are any additional elements recited in the claim beyond the judicial exception(s), and whether those additional elements integrate the exception into a practical application of the exception.
In the present case, the additional limitations beyond the above-noted abstract idea are as follows (where the underlined portions are the “additional limitations” while the bolded portions continue to represent the “abstract idea”):
A display device of a work machine, comprising:
a storage means that stores a cumulative time of use with respect to consumables of the work machine, the consumables including engine oil, an engine oil filter, hydraulic oil, a hydraulic oil return filter, and a hydraulic oil filter that require maintenance depending on use;
the display device that shows a home screen, which includes at least one of the consumables; a notification means; a plurality of function setting means; and a selection means;
the notification means that provides a notification of arrival of a maintenance time of the consumable on the basis of the cumulative time;
the plurality of function setting means for respectively setting in the display device a plurality of functions of the work machine; and
the selection means for selecting any of the plurality of function setting means in the display device, wherein the plurality of function setting means has a reset setting means for resetting the cumulative time, and
the selection means performs visual recognition display that allows visual recognition of a procedure leading to the reset setting means regarding at least one of the consumables for which the maintenance time has arrived,
wherein the notification means provides notification of the arrival of the maintenance time, and the visual recognition display is also performed, on the home screen displayed on the display device wherein the display device allows transition from the home screen to a screen on which the reset setting means is provided,
wherein the notification means provides notification of the arrival of the maintenance time in the same manner on both the home screen and the screen on which the reset setting means is provided.
For the following reason(s), the examiner submits that the above identified additional limitations do not integrate the above-noted abstract idea into a practical application.
Regarding the additional limitations of “storage means”, “notification means”, and “the display device”, the examiner submits that these limitations are mere instructions to apply the above noted abstract idea by merely using a computer to perform the process (MPEP § 2106.05). In particular, “storage means” recited at a high-level of generality (i.e., as ROM performing a generic computer function of storing data) such that it amounts no more than mere instructions to apply the exception using a generic computer component. “notification means” and “the display device” recited at a high-level of generality (i.e., as display performing a generic computer function of displaying a notification and settings) such that it amounts no more than mere instructions to apply the exception using a generic computer component.
Regarding the additional limitations of “a storage means that stores a cumulative time of use with respect to consumables of the work machine, the consumables including engine oil, an engine oil filter, hydraulic oil, a hydraulic oil return filter, and a hydraulic oil filter that require maintenance depending on use”, the examiner submits that these limitations are mere data gathering in conjunction with a law of nature or abstract idea (MPEP § 2106.05). In particular, “a storage means that stores a cumulative time of use” indicate pre-solution activity such that it amounts no more than a step of gathering data for use in a claimed process.
Regarding the additional limitations of “the display device that shows a home screen, which includes at least one of the consumables; a notification means; a plurality of function setting means; and a selection means”, “a notification means that provides a notification of arrival of a maintenance time of the consumable on the basis of the cumulative time”, “the selection means performs visual recognition display that allows visual recognition of a procedure leading to the reset setting means regarding at least one of the consumables for which the maintenance time has arrived”, “wherein the notification means provides notification of the arrival of the maintenance time, and the visual recognition display is also performed, on the home screen displayed on the display device wherein the display device allows transition from the home screen to a screen on which the reset setting means is provided”, and “wherein the notification means provides notification of the arrival of the maintenance time in the same manner on both the home screen and the screen on which the reset setting means is provided”, the examiner submits that these limitations are mere data outputting in conjunction with a law of nature or abstract idea (MPEP § 2106.05). In particular, “the display device that shows a home screen”, “provides a notification of arrival of a maintenance time”, “performs visual recognition display”, “the visual recognition display is also performed, on a home screen displayed on the display device” indicate post-solution activity such that it amounts no more than a step of outputting/displaying data for use in a claimed process.
Thus, taken alone, the additional elements do not integrate the abstract idea into a practical application. Further, looking at the additional limitation(s) as an ordered combination or as a whole, the limitation(s) add no thing that is nor already present when looking at the elements taken individually. For instance, there is no indication that the additional elements, when considered as a whole, reflect an improvement in the functioning of a computer or an improvement to another technology or technical field, apply or use the above-noted judicial exception to effect a particular treatment or prophylaxis for a disease or medical condition, implement/use the above-noted judicial exception with a particular machine or manufacture that is integral to the claim, effect a transformation or reduction of a particular article to a different state or thing, or apply or use the judicial exception in some other meaningful way beyond generally linking the use of the judicial exception to a particular technological environment. Such that the claim as a whole is not more than a drafting effort designed to monopolize the exception (MPEP § 2 106.05). Accordingly, the additional limitation(s) do/does not integrate the abstract idea into a practical application because it does not impose any meaningful limits on practicing the abstract idea.
101 Analysis-Step 2B
Regarding Step 2B of the Revised Guidance, representative independent claim 1 does not include additional elements (considered both individually and as an ordered combination) that are sufficient to amount to significantly more than the judicial exception for the same reasons to those discussed above with respect to determining that the claim does not integrate the abstract idea into a practical application. As discussed above with respect to integration of the abstract idea into a practical application, the additional elements of “storage means”, “notification means”, and “the display device” amounts to nothing more than mere instructions to apply the exception using generic computer components. Mere instructions to apply an exception using generic computer component cannot provide an inventive concept.
Furthermore, regarding the additional limitation of “a storage means that stores a cumulative time of use with respect to consumables of the work machine, the consumables including engine oil, an engine oil filter, hydraulic oil, a hydraulic oil return filter, and a hydraulic oil filter that require maintenance depending on use”, “the display device that shows a home screen, which includes at least one of the consumables; a notification means; a plurality of function setting means; and a selection means”, “the notification means that provides a notification of arrival of a maintenance time of the consumable on the basis of the cumulative time”, “the selection means performs visual recognition display that allows visual recognition of a procedure leading to the reset setting means regarding at least one of the consumables for which the maintenance time has arrived”, “wherein the notification means provides notification of the arrival of the maintenance time, and the visual recognition display is also performed, on the home screen displayed on the display device wherein the display device allows transition from the home screen to a screen on which the reset setting means is provided”, and “wherein the notification means provides notification of the arrival of the maintenance time in the same manner on both the home screen and the screen on which the reset setting means is provided” the examiner submits that the limitation merely adds insignificant extra-solution activity to the at least one abstract idea as previously discussed.
Hence the claim is not patent eligible.
Therefore, claim(s) 1 is/are ineligible under 35 U.S.C. 101.
Regarding Claim 2, the claim recites “the selection means hierarchizes the procedure leading to the reset setting means” which further narrowing the abstract idea and fail to integrate the abstract idea into a practical application.
Regarding Claim 3, the claim recites further narrowing limitation on the “the selection means performs the visual recognition display for each hierarchy level” which is merely insignificant extra solution activity and fail to integrate the abstract idea into a practical application.
Regarding Claim 4, the claim recites “the reset setting means is provided for each type of a plurality of the consumables at the lowest layer of the selection means” which further narrowing the abstract idea and fail to integrate the abstract idea into a practical application.
Regarding Claim 5, the claim recites further narrowing limitation on the “the selection means includes identification notations identifying options and displays an identification notation of an option leading to the reset setting means in a different color from another option, as the visual recognition display” which is merely insignificant extra solution activity and fail to integrate the abstract idea into a practical application.
Regarding Claim 6, the claim recites further narrowing limitation on the “the selection means cancels the visual recognition display after resetting the cumulative time by the reset setting means” which is merely insignificant extra solution activity and fail to integrate the abstract idea into a practical application.
As per claim 7, it recites “A work machine including the display device according to claim 1”. having limitations similar to those of claim 1 and therefore is rejected on the same basis.
Claim Interpretation
The following is a quotation of 35 U.S.C. 112(f):
(f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph:
An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked.
As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph:
(A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function;
(B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and
(C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function.
Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function.
Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function.
Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action.
This application includes one or more claim limitations that do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: storage means in claim 1, notification means in claim 1, function setting means in claim 1, selection means in claim 1-6, reset setting means in claim 1-2, 4-6.
Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. In the specification paragraph 24, “The storage unit 12 is a storage means configured with a storage medium such as a ROM and a RAM and stores various information of the display device 10”. Accordingly, the storage means is interpreted as a storage medium such as a ROM and a RAM. In the specification paragraph 45, “the display control unit I1 and the display unit 13 included in the display device 10 function as a notification means that provides a notification of arrival of a maintenance time of the consumable on the basis of the cumulative time”. Accordingly, the notification means is interpreted as a display. In the specification paragraph 27, “the display control unit 11 displays on the display unit 13 a function setting screen 60 having a plurality of function setting means for setting a plurality of functions of the work machine 1 (refer to FIG. 6). For example, the display control unit 11 displays on the display unit 13 a reset setting screen 60a, as the function setting screen 60, having a reset setting means for resetting usage information such as a cumulative time of each consumable of the work machine 1 as a function setting means. The home screen 20 has a selection means for making a selection leading to any of the plurality of function setting means. Furthermore, the display control unit 11 displays on the display unit 13, between the home screen 20 and the function setting screen 60,selection screens 30, 40, and 50 each having a selection means for making a selection leading to any of the plurality of function setting means (refer to FIG. 3, FIG. 4, and FIG. 5). In other words, the display control unit 11 and the display unit 13 function as the function setting means and the selection means”. Accordingly, the function setting means, selection means, reset setting means are interpreted as user selection buttons on a screen.
If applicant does not intend to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph.
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim 1-7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kudou (US20180268620A1) in view of Gronsbell (US20200234515A1) and KINUGAWA (JP2012211478A).
In regards to claim 1, Kudou teaches A display device of a work machine, comprising:

wherein the notification means provides notification of the arrival of the maintenance time in the same manner on both the home screen (Kudou: Fig. 14 element 281; Para 85 “In the maintenance screen image 275 shown in FIG. 14, the item buttons 276, 277, and 278 are provided with respective remaining period display portions 281, 282, and 283. With this, by opening the maintenance screen image 275 by the operation of the operating portion 20, the user can confirm the remaining periods of all the maintenance items. In the example shown in FIG. 14, the remaining period display portion 281 of the periodic inspection item button 276 displays both the remaining travel distance and the remaining time, and each of the remaining period display portion 282 of the tire rotation item button 277 and the remaining period display portion 283 of the oil change item button 278 displays only the remaining travel distance”; i.e. any user interface screen may be configured to function as the system’s home screen) and the screen on which the reset setting means is provided(Kudou: Fig. 15; Para 88 “The periodic inspection setting screen image 376 shown in FIG. 15 displays: a title display portion 380 a showing that the image is the setting screen image for the periodic inspection; an on/off set button 381 a for turning on or off display setting of the information piece about the maintenance timing of the periodic inspection at the center display unit 12 and the maintenance timing display portion 35; a remaining time set button 382 a for setting the remaining time until the maintenance timing; a remaining travel distance set button 383 a for setting the remaining travel distance until the maintenance timing; and a reset button 384 a for resetting the setting of the remaining period to an initial value”; Para 90 “The remaining time set button 382 a is provided with a remaining period display portion 386 a, and the remaining travel distance set button 383 a is provided with a remaining period display portion 387 a. The remaining period display portion 386 a of the remaining time set button 382 a displays the remaining time, and the remaining period display portion 387 a of the remaining travel distance set button 383 a displays the remaining travel distance”).
Yet Kudou do not explicitly teach the consumables including engine oil, an engine oil filter, hydraulic oil, a hydraulic oil return filter, and a hydraulic oil filter that require maintenance depending on use;
the display device that shows a home screen, which includes at least one of the consumables; a notification means; a plurality of function setting means; and a selection means.
However, in the same field of endeavor, Gronsbell teaches the display device that shows a home screen, which includes at least one of the consumables; a notification means; a plurality of function setting means; and a selection means(Gronsbell: Fig. 41; Para 111 “The user interface 22 may include a touch screen display, a speaker, physical buttons, and/or other input/output mechanisms. In an example embodiment, the processor 14 may comprise user interface circuitry configured to control at least some functions of one or more input/output mechanisms. The processor and/or user interface circuitry comprising the processor may be configured to control one or more functions of one or more input/output mechanisms through computer program instructions (for example, software and/or firmware) stored on a memory accessible to the processor (for example, memory device 16, and/or the like)”; Para 309 “FIGS. 41-42 show an example user home screen including a home screen interface in accordance with embodiments of the present disclosure. In the depicted embodiment, links to one or more vehicle diagnostic data sets (e.g., fuel information, battery information, diagnostic alerts - including DTC, maintenance information, recall information, and any other relevant information relating to the vehicle status and health), vehicle historical information (e.g., trip, location history, and the like), and/or additional functionality (e.g., WiFi hotspot) may be depicted”; i.e. the consumables (fuel information, battery information) a notification means (diagnostic alerts - including DTC, maintenance information, recall information, and any other relevant information relating to the vehicle status and health) a plurality of function setting means (additional functionality (e.g., WiFi hotspot)) and a selection means(touch screen display)).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to modify the display device of a work machine of Kudou with the feature of the display device that shows a home screen, which includes at least one of the consumables; a notification means; a plurality of function setting means; and a selection means disclosed by Gronsbell. One would be motivated to do so for the benefit of “monitor and maintain a vehicle in an efficient manner based on sensory data and protection policies” (Gronsbell: Para 2).
Yet the combination of Kudou and Gronsbell do not explicitly teach the consumables including engine oil, an engine oil filter, hydraulic oil, a hydraulic oil return filter, and a hydraulic oil filter that require maintenance depending on use.
However, in the same field of endeavor, KINUGAWA teaches the consumables including engine oil, an engine oil filter, hydraulic oil, a hydraulic oil return filter, and a hydraulic oil filter that require maintenance depending on use(KINUGAWA: Fig. 7a, 7b, 8a, 8b NO. 1, 2, 5, 7, 8; Para 26 “The memory unit 29 includes a cumulative operating time storage means 33 for storing the cumulative operating time (hour meter) of the work machine 1, an inspection timing storage means 34 for storing information regarding the inspection timing of inspection items, and an inspection record storage means 35”; Para 59 “As shown in Figure 7(b), a check mark is placed in the "Completed" column for parts that have been replaced. The "engine oil," "hydraulic fluid," "air cleaner element," "fuel filter cartridge," and "suction filter" all have check marks indicating that replacement is complete. When you check the box, the "wrench" icon disappears, and the current hour meter reading and date are displayed in "Replacement History (Last)". Unchecking the box in the "Implement" column will revert the display to how it was before the box was checked”).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to modify the display device of a work machine of the combination of Kudou and Gronsbell with the feature of the consumables including engine oil, an engine oil filter, hydraulic oil, a hydraulic oil return filter, and a hydraulic oil filter that require maintenance depending on use disclosed by KINUGAWA. One would be motivated to do so for the benefit of “provide a work machine that allows for easy confirmation of inspection history corresponding to the work machine and that can accommodate diverse forms of maintenance” (KINUGAWA: Para 7).
In regards to claim 2, the combination of Kudou, Gronsbell, and KINUGAWA teaches The display device according to claim 1, and Kudou further teaches wherein the selection means hierarchizes the procedure leading to the reset setting means(Kudou: Fig. 13-17; Para 82 “When the command button 71 is executed on the home screen image 70 shown in FIG. 2, the application screen image 171 shown in FIG. 13 is displayed at the center display unit 12.

The remaining time corresponding to Level 2 of the nearness degree falls within a range of 4 days or more and 15 days or less. The remaining time corresponding to Level 3 of the nearness degree falls within a range of 1 day or more and 3 days or less. The remaining time corresponding to Level 4 of the nearness degree is 0 day or less”; Para 77 “In the informing display portion 80, display for informing that at least one of the maintenance items is in the maintenance period is not performed when the nearness degree is Level 1 (see FIG. 7) but is performed when the nearness degree is Level 2, 3, or 4 (see FIGS. 9 to 11). A mode of the display for informing at the informing display portion 80 is not especially limited. For example, by pop-up display of a wrench mark shown in FIGS. 9 to 11, the informing display portion 80 informs that at least one of the maintenance items is in the maintenance period; Para 91 “When the reset button 384 a is executed by the operation of the operating portion 20, the setting of the remaining period is reset to an initial value. Normally, the reset button 384 a is executed after the maintenance”; i.e. display for informing that at least one of the maintenance items is in the maintenance period is not performed (cancels the visual recognition display) when the nearness degree is Level 1 indicating the remaining period is 16 days or more resulting from a reset to an initial value(resetting the cumulative time by the reset setting means)).
In regards to claim 7, the combination of Kudou, Gronsbell, and KINUGAWA teaches The display device according to claim 1, and Kudou further teaches A work machine including the display device according to claims 1(Kudou: Para 10 “A first aspect of the present invention of the present application is a display device of a vehicle, the display device including a display portion configured to display maintenance related information pieces about a plurality of maintenance items of the vehicle”).
