Office Action

§101
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Response to Amendment Applicant's submission filed on 12/23/2025 has been entered. Claim(s) 51-70 is/are pending in the application. Claim Rejections - 35 USC § 101 1. 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 51-70 are rejected under 35 U.S.C. 101 because the claimed invention is directed to a judicial exception (i.e., a law of nature, a natural phenomenon, or an abstract idea) without significantly more. Claim(s) 51 is/are drawn to method (i.e., a process), claim(s) 69 is/are drawn to a system (i.e., a machine/manufacture), and claim(s) 65 is/are drawn to non-transitory computer readable medium (i.e., a machine/manufacture). As such, claims 51, 65, 69 is/are drawn to one of the statutory categories of invention. Claims 51-70 are directed to detect a device that misidentifies itself. Specifically, the claims recite performing a verification of the self-reported identity, comprising over a time greater than one hour, monitoring network traffic from the device to determine whether network traffic over the time is consistent with expected network traffic for the self- reported identity; and upon determining that the network traffic is not consistent, designating the device as potentially deceptively misidentified, and causing a network gateway device to apply heighted security rules to the device, which is grouped within the Mathematical Concepts and is similar to the concept of (mathematical relationships OR mathematical formulas or equations OR mathematical calculations) OR the Methods Of Organizing Human Activity and is similar to the concept of (fundamental economic principles or practices including hedging insurance, mitigating risk) OR (commercial or legal interactions including agreements in the form of contracts, legal obligations, advertising, marketing or sales activities or behaviors business relations) OR (managing personal behavior or relationships or interactions between people including social activities teaching, and following rules or instructions) OR Mental Processes and is similar to the concept of (concepts performed in the human mind (including an observation, evaluation, judgement, opinion) grouping of abstract ideas in prong one of step 2A of the Alice/Mayo test (See 2019 Revised Patent Subject Matter Eligibility Guidance, 84 Fed. Reg. 50, 52, 54 (January 7, 2019)). Accordingly, the claims recite an abstract idea (See pages 7, 10, Alice Corporation Pty. Ltd. v. CLS Bank International, et al., US Supreme Court, No. 13-298, June 19, 2014; 2019 Revised Patent Subject Matter Eligibility Guidance, 84 Fed. Reg. 50, 53-54 (January 7, 2019)). This judicial exception is not integrated into a practical application because, when analyzed under prong two of step 2A of the Alice/Mayo test (See 2019 Revised Patent Subject Matter Eligibility Guidance, 84 Fed. Reg. 50, 54-55 (January 7, 2019)), the additional element(s) of the claim(s) such as one or more tangible, nontransitory, computer-readable storage, hardware platform, memory, and a processor merely use(s) a computer as a tool to perform an abstract idea and/or generally link(s) the use of a judicial exception to a particular technological environment. Specifically, the one or more tangible, nontransitory, computer-readable storage, hardware platform, memory, and a processor perform(s) the steps or functions of sending, to the device, discovery probes, and receiving in response to the discovery probes a self-reported identity. The use of a processor/computer as a tool to implement the abstract idea and/or generally linking the use of the abstract idea to a particular technological environment does not integrate the abstract idea into a practical application because it requires no more than a computer performing functions that correspond to acts required to carry out the abstract idea. The additional elements do not involve improvements to the functioning of a computer, or to any other technology or technical field (MPEP 2106.05(a)), the claims do not apply or use the abstract idea to effect a particular treatment or prophylaxis for a disease or medical condition (Vanda Memo), the claims do not apply the abstract idea with, or by use of, a particular machine (MPEP 2106.05(b)), the claims do not effect a transformation or reduction of a particular article to a different state or thing (MPEP 2106.05(c)), and the claims do not apply or use the abstract idea in some other meaningful way beyond generally linking the use of the abstract idea to a particular technological environment, such that the claim as a whole is more than a drafting effort designed to monopolize the exception (MPEP 2106.05(e) and Vanda Memo). Therefore, the claims do not, for example, purport to improve the functioning of a computer. Nor do they effect an improvement in any other technology or technical field. Accordingly, the additional elements do not impose any meaningful limits on practicing the abstract idea, and the claims are directed to an abstract idea. The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because, when analyzed under step 2B of the Alice/Mayo test (See 2019 Revised Patent Subject Matter Eligibility Guidance, 84 Fed. Reg. 50, 52, 56 (January 7, 2019)), the additional element(s) of using a one or more tangible, nontransitory, computer-readable storage, hardware platform, memory, and a processor to perform the steps amounts to no more than using a computer or processor to automate and/or implement the abstract idea of detect a device that misidentifies itself. As discussed above, taking the claim elements separately, the one or more tangible, nontransitory, computer-readable storage, hardware platform, memory, and a processor perform(s) the steps or functions of sending, to the device, discovery probes, and receiving in response to the discovery probes a self-reported identity. These functions correspond to the actions required to perform the abstract idea. Viewed as a whole, the combination of elements recited in the claims merely recite the concept of detect a device that misidentifies itself. Therefore, the use of these additional elements does no more than employ the computer as a tool to automate and/or implement the abstract idea. The use of a computer or processor to merely automate and/or implement the abstract idea cannot provide significantly more than the abstract idea itself (MPEP 2106.05(I)(A)(f) & (h)). Therefore, the claim is not patent eligible. Dependent claims 52-64, 66-68, 70 further describe the abstract idea of detect a device that misidentifies itself. The dependent claims do not include additional elements that integrate the abstract idea into a practical application or that provide significantly more than the abstract idea. Therefore, the dependent claims are also not patent eligible. Response to Arguments Applicant's arguments filed 12/23/2025 have been fully considered but they are not persuasive. A. Applicant argues that the claims are not directed to a judicial exception under Step 2A Prong One. As for Step 2A Prong One, of the Abstract idea is directed towards the abstract idea of detect a device that misidentifies itself which is grouped within the Mathematical Concepts and is similar to the concept of (mathematical relationships OR mathematical formulas or equations OR mathematical calculations) OR Methods Of Organizing Human Activity and is similar to the concept of (fundamental economic principles or practices including hedging insurance, mitigating risk) OR (commercial or legal interactions including agreements in the form of contracts, legal obligations, advertising, marketing or sales activities or behaviors business relations) OR (managing personal behavior or relationships or interactions between people including social activities teaching, and following rules or instructions) OR Mental Processes and is similar to the concept of (concepts performed in the human mind (including an observation, evaluation, judgement, opinion) grouping of abstract ideas in prong one of step 2A of the Alice/Mayo test (See 2019 Revised Patent Subject Matter Eligibility Guidance, 84 Fed. Reg. 50, 52, 54 (January 7, 2019)). Accordingly, the claims recite an abstract idea (See pages 7, 10, Alice Corporation Pty. Ltd. v. CLS Bank International, et al., US Supreme Court, No. 13-298, June 19, 2014; 2019 Revised Patent Subject Matter Eligibility Guidance, 84 Fed. Reg. 50, 53-54 (January 7, 2019)). B. Applicant argues that the claims are not directed to a judicial exception under Step 2A Prong Two. As for Step 2A Prong Two, the claim limitations do not include additional elements in the claim that apply, rely on, or use the judicial exception in a manner that imposes a meaningful limit on the judicial exception, and the claim is not more than a drafting effort designed to monopolize the judicial exception and the claim limitation simply describe the abstract idea. The limitation directed to detect a device that misidentifies itself does not add technical improvement to the abstract idea. The recitations to one or more tangible, nontransitory, computer-readable storage, hardware platform, memory, and a processor perform(s) the steps or functions of sending, to the device, discovery probes, and receiving in response to the discovery probes a self-reported identity. The use of a processor/computer as a tool to implement the abstract idea and/or generally linking the use of the abstract idea to a particular technological environment does not integrate the abstract idea into a practical application because it requires no more than a computer performing functions that correspond to acts required to carry out the abstract idea. The additional elements do not involve improvements to the functioning of a computer, or to any other technology or technical field (MPEP 2106.05(a)), the claims do not apply or use the abstract idea to effect a particular treatment or prophylaxis for a disease or medical condition (Vanda Memo), the claims do not apply the abstract idea with, or by use of, a particular machine (MPEP 2106.05(b)), the claims do not effect a transformation or reduction of a particular article to a different state or thing (MPEP 2106.05(c)), and the claims do not apply or use the abstract idea in some other meaningful way beyond generally linking the use of the abstract idea to a particular technological environment, such that the claim as a whole is more than a drafting effort designed to monopolize the exception (MPEP 2106.05(e) and Vanda Memo). Therefore, the claims do not, for example, purport to improve the functioning of a computer. Nor do they effect an improvement in any other technology or technical field. Accordingly, the additional elements do not impose any meaningful limits on practicing the abstract idea, and the claims are directed to an abstract idea. C. Applicant argues that the claims are not directed to a judicial exception under Step 2B. As for Step 2B, The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because, when analyzed under step 2B of the Alice/Mayo test (See 2019 Revised Patent Subject Matter Eligibility Guidance, 84 Fed. Reg. 50, 52, 56 (January 7, 2019)), the limitation directed to detect a device that misidentifies itself does not add significantly more to the abstract idea. Furthermore, using well-known computer functions to execute an abstract idea does not constitute significantly more. The recitations to one or more tangible, nontransitory, computer-readable storage, hardware platform, memory, and a processor are generically recited computer structure. These functions correspond to the actions required to perform the abstract idea. Viewed as a whole, the combination of elements recited in the claims merely recite the concept of detect a device that misidentifies itself. Therefore, the use of these additional elements does no more than employ the computer as a tool to automate and/or implement the abstract idea. The use of a computer or processor to merely automate and/or implement the abstract idea cannot provide significantly more than the abstract idea itself (MPEP 2106.05(I)(A)(f) & (h)). Therefore, the claim is not patent eligible. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure and located in the PTO-892 form. 1.Cao, U.S. Patent 9473413, teaches techniques for dynamically throttling network traffic may be provided. For example, a first threshold specific to a first client may be determined and may be dynamically adjusted over time. A volume of network traffic of the first client may be compared to the first threshold and, if is in excess, a throttling operation may be performed. The throttling operation may include throttling the network traffic of the first client, throttling the traffic of a second client, or comparing the volume of network traffic to a second threshold. If the second threshold is exceeded, a connection with the first client or the second client may be terminated. 2. Kosciewicz, U.S. Patent App 20120260277, teaches a system for monitoring the quality of DRM-protected multimedia data streams, the system comprising at least one computer having a network connection to receive at least one said DRM-protected multimedia data stream, program memory, working memory, and a processor coupled to said program memory, working memory, and wherein said program memory stores processor control code for a media player for said multimedia data stream and code to control said processor to: play said DRM-protected multimedia data stream to provide at least a decrypted video data output stream for display on a monitor; capture still image data from a succession of still images from said video data output stream; process said still image data to detect greater than a threshold difference between at least two of said still images; and output fault data identifying a potential video quality fault responsive to absence of detection of said greater than a threshold difference.
