Office Action

§101 §103
DETAILED ACTION Claims 1-22 rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more.

(US 2010/0277411 A1) as applied in claims 6: 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 1-22 rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. Step zero: establish broadest reasonable interpretation as shown in footnotes throughout this Office action; Step 1: Claim 1 is a machine; claim 11 a manufacture; claim 21 a process; Step 2A, prong 1: The claim(s) recite(s) a mental process and math: Claim 21 (representative of claims 11 & 21): obtaining captured images… determining fitting closed curves to the observed edges… selecting a closed curve from a family of similar closed curves…using an assumed parameter1… using fitted closed curves: 21. (Currently Amended) A method for determining a gesture2 command3 from analysis of differences in positions of fit closed curves fit to observed edges of a control object to track motion of the control object while making a gesture in a 3D space, including repeatedly: obtaining captured images of a control object moving in 3D space; determining fitting4 closed curves to the observed edges of the control object, including control object appendages for multiple portions of any complex control objects, as captured5 in the captured images by selecting a closed curve from a family6 of similar closed curves that fit the observed edges of the control object as captured using an assumed parameter; and constructing, using fitted closed curves,in 3D space from multiple portions of any complex control objects and one or more of control object appendages appended thereto. Step 2A, prong 2: This mental & math judicial exception is not integrated into a practical application because the additional elements (“captured images” “control object” “processor” “medium” “making a gesture” & computer stuff) do not improve technology or a technical field or the function of a computer in view of applicant’s disclosure: PNG media_image1.png 1165 1125 media_image1.png Greyscale Step 2B: The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because each additional element, such as “captured images” “control object” “processor” “medium” “making a gesture” & computer stuff, considered individually or with the mental process & math adheres to conventional practices as indicated in applicant’s specification’s background7: PNG media_image2.png 1565 1121 media_image2.png Greyscale Suggestions MPEP 2106.07(a) Formulating a Rejection For Lack of Subject Matter Eligibility [R-07.2022] II. WHEN MAKING A REJECTION, EXPLAIN WHY THE ADDITIONAL CLAIM ELEMENTS DO NOT RESULT IN THE CLAIM AS A WHOLE INTEGRATING THE JUDICIAL EXCEPTION INTO A PRACTICAL APPLICATION OR AMOUNTING TO SIGNIFICANTLY MORE THAN THE JUDICIAL EXCEPTION (STEP 2A PRONG TWO AND STEP 2B), last para: In the event a rejection is made, it is a best practice for the examiner to consult the specification [0007] to determine if there are elements (“the light sources are arranged, for example, in a line or a plane such that the true intersection points are determined without identifying the actual locations thereof; this reduces the computational complexity, thereby increasing the processing speed8”) that could be added to the claim to make it eligible. If so, the examiner should identify those elements in the Office action and suggest them as a way to overcome the rejection. Applicant’s disclosure: [0007] Embodiments of the present invention relate to methods and systems for capturing motion and/or determining the shapes and positions of one or more objects in 3D space using at least one cross-section thereof; the cross-section(s) may be obtained from, for example, reflections from the object or shadows cast by the object. In various embodiments, the 3D reflections or shadows captured using a camera are first sliced into multiple two-dimensional (2D) cross-sectional images. The cross-sectional position and shape (or “intersection region”) of the 3D objects in each 2D slice may be determined based on the positions of one or more light sources used to illuminate the objects and the captured reflections or shadows. The 3D structure of the object may then be reconstructed by assembling a collection of the intersection regions obtained in the 2D slices. In some embodiments, the 2D intersection regions are identified based on “true” intersection points — i.e., points within the volume defined by the intersection of all light beams, which volume includes the object. These true intersection points may determined by the light sources and reflections or shadows — e.g., based on the number of reflection or shadow regions that they lie within or the locations of the geometric projection points calculated based on the positions of the light sources. In one embodiment, the light sources are arranged, for example, in a line or a plane such that the true intersection points are determined without identifying the actual locations thereof; this reduces the computational complexity, thereby increasing the processing speed. In some embodiments, the intersection region is split into a number of smaller intersection regions that can individually represent at least a portion of the reflections or shadows in the scene. Because determining each of the smaller intersection regions is computationally simpler than determining the entire intersection region, the processing time for obtaining the entire intersection region assembled from the individual smaller intersection regions is reduced (even if the smaller intersection regions are determined sequentially rather than in parallel). In various embodiments, the number of small split intersection regions that need to be identified is reduced by setting a criteria number U equal to the greatest number of intersection points in any intersection region; only regions or combinations of regions having a number of intersection points exceeding the criteria number U are further processed to identify the intersection regions therein. Response to Arguments Applicant's arguments filed 6/18/2026 have been fully considered but they are not persuasive: Subject Matter Eligibility Rejection In response to applicant's argument that the references fail to show certain features of the invention, it is noted that the features upon which applicant relies (i.e., page 10, 3rd para: “computer vision using markerless 3D hand/control object tracking”) are not recited in the rejected claim(s). Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). Step 2A Mental Processes Applicant’s state in page 11, penult para: For example, the human mind is not equipped to (i) fit "closed curves to the observed edges of the control object, including control object appendages for multiple portions of any complex control objects, as captured in the captured images by selecting a closed curve from a family of similar closed curves that fit the observed edges of the control object as captured using an assumed parameter" or (ii) construct, "using fitted closed curves, a complex control object in 3D space from multiple portions of any complex control objects and one or more of control object appendages appended thereto." The examiner respectfully disagrees since the claimed fit9 is/recites10 math or a single- or multiple-valued function. The claimed “constructing”11 is an abstract idea or mental process comprising contriving, planning, elaborating, inventing from existing ideas. Mathematical Formulas The MPEP defines the mathematical concepts grouping as "mathematical relationships, mathematical formulas or equations, and mathematical calculations." MPEP § 2106.04(a)(2)(1). It further notes that, "[w]hen determining whether a claim recites a mathematical concept (i.e., mathematical relationships, mathematical formulas or equations, and mathematical calculations), examiners should consider whether the claim recites a mathematical concept or merely limitations that are based on or involve a mathematical concept. A claim does not recite a mathematical concept (i.e., the claim limitations do not fall within the mathematical concept grouping), if it is only based on or involves a mathematical concept." Id The Office Action characterizes the claims as being directed to "math." However, although Claims 1-22 may include calculations and/or determinations, they do not recite a mathematical concept. The examiner respectfully disagrees since the claimed fit12 is/recites13 math or a single- or multiple-valued function. Thus the claimed “fit” is a calculation of a value according to14 or contingent on a single- or multiple-valued function based on data. Step 2A – Prong Two In response to applicant's argument that the references fail to show certain features of the invention, it is noted that the features upon which applicant relies (i.e., page 12, last para: “computer vision using markerless 3D hand/control object tracking”) are not recited in the rejected claim(s). Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). In response to applicant's argument that the references fail to show certain features of the invention, it is noted that the features upon which applicant relies (i.e., page 13, 2nd para: “computer vision using markerless 3D hand/control object tracking”) are not recited in the rejected claim(s). Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). Step 2B In response via the 35 USC 101 rejection: “The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because each additional element, such as “captured images” “control object” “processor” “medium” “making a gesture” & computer stuff, considered individually or with the mental process & math adheres to conventional practices as indicated in applicant’s specification’s background”. Non-Statutory Double Patenting Rejections Applicant’s arguments, see remarks, page 13, filed 6/18/2026, with respect to double patenting have been fully considered and are persuasive. The double patenting of US Patents: 9,070,019; 9,945,660; 10,767,982; 11,994,377 has been withdrawn. Art Rejections of Claims 1,11, and 21 Applicant's arguments filed 6/18/2026 have been fully considered but they are not persuasive: In response to applicant's argument that the references fail to show certain features of the invention, it is noted that the features upon which applicant relies (i.e., page 14, 4th para: “image-analysis operations…automatic repeated processing” ) are not recited in the rejected claim(s). Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). Applicants state in page 15: As noted, Muncey is directed to techniques for creating, modifying, and correlating 3D models with 2D pictures. In Muncey, the user interacts with a 2D image by placing or dragging control elements, such as the handles of a wireframe cage, onto corresponding points or edges in the image. The system then determines the position and orientation of the modeled 3D object and projects it onto the image plane. Therefore, at most, Muncey could be understood as addressing user-assisted 3D modelling from a static 2D image or placement of a pre-existing 3D model into a 2D scene. However, Muncey does not disclose, teach, or suggest a system for recognizing gestures from a control object moving in 3D space. Nor does Muncey disclose, teach, or suggest "repeatedly obtaining captured images of a control object moving in 3D space," "determining observed edges of the control object from those captured images," and "fitting closed curves to the observed edges of the control object, including appendages or multiple portions of complex control objects." In response, the claimed “for recognizing gestures” “is not considered a limitation and is of no significance to claim construction” “to the structure and process of making” (claim 1s “constructing…a complex control object”) “when the claim body describes a structurally complete invention such that deletion of the preamble phrase does not affect the structure or steps of the claimed invention” since the body of claim 1 “fully and intrinsically sets forth all of the limitations of the claimed invention” via MPEP 2111.02: MPEP Effect of Preamble [R-07.2022] 2111.02 II. PREAMBLE STATEMENTS RECITING PURPOSE OR INTENDED USE, 1st para: The claim preamble must be read in the context of the entire claim. The determination of whether preamble recitations are structural limitations or mere statements of purpose or use "can be resolved only on review of the entirety of the [record] to gain an understanding of what the inventors actually invented and intended to encompass by the claim" as drafted without importing "‘extraneous’ limitations from the specification." Corning Glass Works, 868 F.2d at 1257, 9 USPQ2d at 1966. If the body of a claim fully and intrinsically sets forth all of the limitations of the claimed invention, and the preamble merely states, for example, the purpose or intended use of the invention, rather than any distinct definition of any of the claimed invention’s limitations, then the preamble is not considered a limitation and is of no significance to claim construction. Shoes by Firebug LLC v. Stride Rite Children’s Grp., LLC, 962 F.3d 1362, 2020 USPQ2d 10701 (Fed. Cir. 2020) (The court found that the preamble in one patent’s claim is limiting but is not in a related patent); Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1305, 51 USPQ2d 1161, 1165 (Fed. Cir. 1999). See also Rowe v. Dror, 112 F.3d 473, 478, 42 USPQ2d 1550, 1553 (Fed. Cir. 1997) ("where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention, the preamble is not a claim limitation"); Kropa v. Robie, 187 F.2d at 152, 88 USPQ2d at 480-81 (preamble is not a limitation where claim is directed to a product and the preamble merely recites a property inherent in an old product defined by the remainder of the claim); STX LLC. v. Brine, 211 F.3d 588, 591, 54 USPQ2d 1347, 1350 (Fed. Cir. 2000) (holding that the preamble phrase "which provides improved playing and handling characteristics" in a claim drawn to a head for a lacrosse stick was not a claim limitation). Compare Jansen v. Rexall Sundown, Inc., 342 F.3d 1329, 1333-34, 68 USPQ2d 1154, 1158 (Fed. Cir. 2003) (In a claim directed to a method of treating or preventing pernicious anemia in humans by administering a certain vitamin preparation to "a human in need thereof," the court held that the preamble is not merely a statement of effect that may or may not be desired or appreciated, but rather is a statement of the intentional purpose for which the method must be performed. Thus the claim is properly interpreted to mean that the vitamin preparation must be administered to a human with a recognized need to treat or prevent pernicious anemia.); Nantkwest , Inc. v. Lee, 686 Fed. App'x 864, 867 (Fed. Cir. 2017) (nonprecedential) (The court found that the preamble phrase "treating a cancer" "’require[s] lysis of many cells, in order to accomplish the goal of treating cancer’ and not merely lysing one or a few cancer cells."); In re Cruciferous Sprout Litig., 301 F.3d 1343, 1346-48, 64 USPQ2d 1202, 1204-05 (Fed. Cir. 2002) (A claim at issue was directed to a method of preparing a food rich in glucosinolates wherein cruciferous sprouts are harvested prior to the 2-leaf stage. The court held that the preamble phrase "rich in glucosinolates" helps define the claimed invention, as evidenced by the specification and prosecution history, and thus is a limitation of the claim (although the claim was anticipated by prior art that produced sprouts inherently "rich in glucosinolates")). During examination, statements in the preamble reciting the purpose or intended use of the claimed invention must be evaluated to determine whether or not the recited purpose or intended use results in a structural difference (or, in the case of process claims, manipulative difference) between the claimed invention and the prior art. If so, the recitation serves to limit the claim. See, e.g., In re Otto, 312 F.2d 937, 938, 136 USPQ 458, 459 (CCPA 1963) (The claims were directed to a core member for hair curlers and a process of making a core member for hair curlers. The court held that the intended use of hair curling was of no significance to the structure and process of making.); In re Sinex, 309 F.2d 488, 492, 135 USPQ 302, 305 (CCPA 1962) (statement of intended use in an apparatus claim did not distinguish over the prior art apparatus). To satisfy an intended use limitation which is limiting, a prior art structure which is capable of performing the intended use as recited in the preamble meets the claim. See, e.g., In re Schreiber, 128 F.3d 1473, 1477, 44 USPQ2d 1429, 1431 (Fed. Cir. 1997) (anticipation rejection affirmed based on Board’s factual finding that the reference dispenser (a spout disclosed as useful for purposes such as dispensing oil from an oil can) would be capable of dispensing popcorn in the manner set forth in appellant’s claim 1 (a dispensing top for dispensing popcorn in a specified manner)) and cases cited therein. See also MPEP § 2112 - MPEP § 2112.02. However, a "preamble may provide context for claim construction, particularly, where … that preamble’s statement of intended use forms the basis for distinguishing the prior art in the patent’s prosecution history." Metabolite Labs., Inc. v. Corp. of Am. Holdings, 370 F.3d 1354, 1358-62, 71 USPQ2d 1081, 1084-87 (Fed. Cir. 2004). The patent claim at issue was directed to a two-step method for detecting a deficiency of vitamin B12 or folic acid, involving (i) assaying a body fluid for an "elevated level" of homocysteine, and (ii) "correlating" an "elevated" level with a vitamin deficiency. Id. at 1358-59, 71 USPQ2d at 1084. The court stated that the disputed claim term "correlating" can include comparing with either an unelevated level or elevated level, as opposed to only an elevated level because adding the "correlating" step in the claim during prosecution to overcome prior art tied the preamble directly to the "correlating" step. Id. at 1362, 71 USPQ2d at 1087. The recitation of the intended use of "detecting" a vitamin deficiency in the preamble rendered the claimed invention a method for "detecting," and, thus, was not limited to detecting "elevated" levels. Id. See also Catalina Mktg. Int’l, 289 F.3d at 808-09, 62 USPQ2d at 1785 ("[C]lear reliance on the preamble during prosecution to distinguish the claimed invention from the prior art transforms the preamble into a claim limitation because such reliance indicates use of the preamble to define, in part, the claimed invention.…Without such reliance, however, a preamble generally is not limiting when the claim body describes a structurally complete invention such that deletion of the preamble phrase does not affect the structure or steps of the claimed invention." Consequently, "preamble language merely extolling benefits or features of the claimed invention does not limit the claim scope without clear reliance on those benefits or features as patentably significant."). In Poly-America LP v. GSE Lining Tech. Inc., 383 F.3d 1303, 1310, 72 USPQ2d 1685, 1689 (Fed. Cir. 2004), the court stated that "a ‘[r]eview of the entirety of the ’047 patent reveals that the preamble language relating to ‘blown-film’ does not state a purpose or an intended use of the invention, but rather discloses a fundamental characteristic of the claimed invention that is properly construed as a limitation of the claim.’" Compare Intirtool, Ltd. v. Texar Corp., 369 F.3d 1289, 1294-96, 70 USPQ2d 1780, 1783-84 (Fed. Cir. 2004) (holding that the preamble of a patent claim directed to a "hand-held punch pliers for simultaneously punching and connecting overlapping sheet metal" was not a limitation of the claim because (i) the body of the claim described a "structurally complete invention" without the preamble, and (ii) statements in prosecution history referring to "punching and connecting" function of invention did not constitute "clear reliance" on the preamble needed to make the preamble a limitation). 1. (Currently Amended) A system [[for recognizing gestures]]15 from a control object moving in three dimensional (3D) space, the system including: one or more processors coupled to a memory, the memory loaded with computer instructions that, when executed by the one or more processors, implement actions to analyze differences in positions of fit closed curves fit to observed edges of a control object to enable tracking motion of the control object while making a gesture in a 3D space, by repeatedly: obtaining captured images of a control object moving in 3D space; determining fitting closed curves to the observed edges of the control object, including control object appendages for multiple portions of any complex control objects, as captured in the captured images by selecting a closed curve from a family of similar closed curves that fit the observed edges of the control object as captured using an assumed parameter; and constructing, using fitted closed curves, 3D space from multiple portions of any complex control objects and one or more of control object appendages appended thereto. Applicant’s arguments rely on language solely recited in preamble recitations in claim(s) 1. When reading the preamble in the context of the entire claim, the recitation “for recognizing gestures” is not limiting because the body of the claim describes a complete invention and the language recited solely in the preamble does not provide any distinct definition of any of the claimed invention’s limitations. Thus, the preamble of the claim(s) is not considered a limitation and is of no significance to claim construction. See Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1305, 51 USPQ2d 1161, 1165 (Fed. Cir. 1999). See MPEP § 2111.02. Thus Muncey discloses "repeatedly obtaining captured images of a control object moving in 3D space," "determining observed edges of the control object from those captured images," and "fitting closed curves to the observed edges of the control object, including appendages or multiple portions of complex control objects." In response to applicant's argument that the references fail to show certain features of the invention, it is noted that the features upon which applicant relies (i.e., page 15, 3rd para, 3rd S: “observed edges calculated”) are not recited in the rejected claim(s). Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). In response to applicant's arguments against the references individually, one cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981); In re Merck & Co., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986). Hindsight Analysis In response to applicant's argument that the references fail to show certain features of the invention, it is noted that the features upon which applicant relies (i.e., page 17, 1st para, 2nd S: “markerless 3D tracking”) are not recited in the rejected claim(s). Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). In response to applicant's argument that the examiner's conclusion of obviousness is based upon improper hindsight reasoning, it must be recognized that any judgment on obviousness is in a sense necessarily a reconstruction based upon hindsight reasoning. But so long as it takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made, and does not include knowledge gleaned only from the applicant's disclosure, such a reconstruction is proper. See In re McLaughlin, 443 F.2d 1392, 170 USPQ 209 (CCPA 1971). Claim Rejections - 35 USC § 103 The following is a quotation of pre-AIA 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action: (a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negated by the manner in which the invention was made.

Language (“any complex control objects and one or more of control object appendages appended thereto”) that suggests or makes a feature or step optional but does not require that feature or step does not limit the scope of a claim under the broadest reasonable claim interpretation. In addition, when a claim requires selection of an element from a list of alternatives, the prior art teaches the element if one of the alternatives is taught by the prior art. See, e.g., Fresenius USA, Inc. v. Baxter Int’l, Inc., 582 F.3d 1288, 1298, 92 USPQ2d 1163, 1171 (Fed.

Under the flexible inquiry set forth by the Supreme Court, the district court therefore erred by failing to take account of ‘the inferences and creative steps,’ or even routine steps, that an inventor would employ and by failing to find a motivation to combine related pieces from the prior art." Ball Aerosol, 555 F.3d at 993, 89 USPQ2d at 1877. 33 This intended use preamble language “for recognizing gestures from a control object moving in three dimensional (3D) space” does not serve to limit or redefine the remainder of system claim 1. 34 This intended use preamble language (for claim 6) “to analyze differences in positions of fit closed curves fit to observed edges of a control object to enable tracking motion of the control object while making a gesture in a 3D space” does not serve to limit or redefine the remainder of system claim 1. 35 Claim 1, lines 1-6 is the preamble: a similar analysis applies to claims 21 and 11. 36 Claim 11, lines 1-5 is the preamble: a similar analysis applied to claims 1 and 21 37 handle: a part of a thing made specifically to be grasped or held by the hand.

"ADAPTED TO," "ADAPTED FOR," "WHEREIN," and "WHEREBY” : Claim scope is not limited by claim language that suggests or makes optional but does not require steps to be performed, or by claim language that does not limit a claim to a particular structure. However, examples of claim language, although not exhaustive, that may raise a question as to the limiting effect of the language in a claim are: (A) "adapted to" or "adapted for" clauses; (B) "wherein" clauses; and (C) "whereby" clauses. The determination of whether each of these clauses is a limitation in a claim depends on the specific facts of the case. See, e.g., Griffin v. Bertina, 285 F.3d 1029, 1034, 62 USPQ2d 1431 (Fed. Cir. 2002) (finding that a "wherein" clause limited a process claim where the clause gave "meaning and purpose to the manipulative steps"). 57 wherein: in what or in which, wherein which is defined: (used relatively in restrictive and nonrestrictive clauses to represent a specified antecedent [i.e., claim 1, line 6’s:“to enable tracking motion of the control object while making a gesture”]). (Dictionary.com) 58 “wherein” is interpreted to refer to claim 4 “tracking motion of the control object while making a gesture in a 3D space further includes:” and not necessarily referring to similar language in claim 1’ preamble under the broadest reasonable interpretation of claims 1,4,6. 59 tracking: to follow (a track, course, etc.). (Dictionary.com) 60 The preamble’s “tracking” is not apparent in the remainder of claims 1,4,6 and thus not a limitation. 61 gesture: a movement or position of the hand, arm, body, head, or face that is expressive of an idea, opinion, emotion, etc..(Dictionary.com) 62 The preamble’s “gesture” is not apparent in the remainder of claims 1,4,6 and thus not a limitation. 63 and: (used to connect alternatives). (Dictionary.com) 64 The crossed text “does not limit the scope” via MPEP 2143.03    All Claim Limitations Must Be Considered [R-01.2024],3rd para: As a general matter, the grammar and ordinary meaning of terms (“and”) as understood by one having ordinary skill in the art used in a claim will dictate whether, and to what extent, the language limits the claim scope. Language (“any complex control objects and one or more of control object appendages appended thereto”) that suggests or makes a feature or step optional but does not require that feature or step does not limit the scope of a claim under the broadest reasonable claim interpretation. In addition, when a claim requires selection of an element from a list of alternatives, the prior art teaches the element if one of the alternatives is taught by the prior art. See, e.g., Fresenius USA, Inc. v. Baxter Int’l, Inc., 582 F.3d 1288, 1298, 92 USPQ2d 1163, 1171 (Fed. Cir. 2009). 65 determine: to conclude or ascertain, as after reasoning, observation, etc., wherein conclude is defined: to bring to a decision or settlement; settle or arrange finally, wherein settlement is defined: the act of making stable or putting on a permanent basis, wherein make is defined: to establish or enact; put into existence, wherein establish is defined: to found (found is the identity of base), institute, build, or bring into being on a firm or stable basis, wherein found is defined: to base or ground (usually followed by on or upon ) (Dictionary.com) 66 compare: to examine (two or more objects, ideas, people, etc.) in order to note similarities and differences. (Dictionary.com) 67 MPEP 2143.03 All Claim Limitations Must Be Considered [R-01.2024], 2nd para: Examiners must consider all claim limitations when determining patentability of an invention over the prior art. In re Gulack, 703 F.2d 1381, 1385, 217 USPQ 401, 403-04 (Fed. Cir. 1983). The subject matter of a properly construed claim is defined by the terms that limit the scope of the claim when given their broadest reasonable interpretation. In Axonics, Inc. v. Medtronic, Inc., 73 F.4th 950, 958-59, 2023 USPQ2d 795 (Fed. Cir. 2023), the court found the claims were improperly narrowed based on a preferred embodiment to sacral anatomy or sacral neuromodulation, whereas the patent claims made no reference to sacral anatomy or sacral neuromodulation. Thus, the relevant prior art was improperly limited to a narrow subset of claim scope. See also MPEP § 2111 et seq. It is the subject matter of the properly construed claim that must be examined. The determination of whether particular language is a limitation in a claim depends on the specific facts of the case. See, e.g., Griffin v. Bertina, 285 F.3d 1029, 1034, 62 USPQ2d 1431 (Fed. Cir. 2002). 68 while: at the same time that (showing an analogous or corresponding action) (Dictionary.com) 69 “making” is a present particle participating with the action of “tracks 808” in the present tense, wherein present participle is defined: a participial form of verbs (make) used adjectivally when the action it describes is contemporaneous with that of the main verb (track) of a sentence and also used in the formation of certain compound tenses.
