The patent application relates to a system for analyzing a time series signal by a method based on Chaos Theory and calculating a chaos theoretical exponent value (CTEV) thereof. The patent application claims an application of the method disclosed in the description for analyzing a speech signal.<\/span><br \/>\n<span style=\"font-size: 12pt;\">The Deputy Controller, Delhi Patent Office rejected the application under section 3(ka) stating that the patent application merely claimed a mathematical method and rejected the argument from the applicant that the technical effect claimed (analyzing a speech signal) makes the invention patentable.\u00a0 The applicant appealed the Deputy Controller&#8217;s decision before the IPAB.<\/span><br \/>\n<span style=\"font-size: 12pt;\">The IPAB upheld the order of the Deputy Controller and stated that as per the rulings of the IPAB in Yahoo vs. Rediff (where the IPAB had ruled that an inventive step, which is a technical advance compared to the existing knowledge, would not give the applicant the right to a patent as such, if the subject matter of the inventive step is an excluded subject itself) and UK (United Kingdom) decisions (Symbian vs. Comptroller of Patents (supra); Gameaccount Ltd., T. 543\/2006), the patent application is not patentable (hereby agreeing with the decision of the Deputy Controller) as the technical advance was merely a mathematical method and mathematical methods fall under excluded subject matter (under section 3(ka)).<\/span><\/p>\n<p><span style=\"font-size: 12pt;\">This decision provides further clarity on patentable subject matter and is in line with 3.17 of the recent <a href=\"http:\/\/www.ipindia.nic.in\/iponew\/draft_Guidelines_CRIs_28June2013.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">draft guidelines<\/a> released by the Indian Patent Office.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The IPAB upheld the rejection of a patent application involving mathematical methods under section 3(ka) of the Indian Patents Act.
