Office Action

§101
DETAILED ACTION 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 . 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. Claim 1-6 are rejected under 35 U.S.C. 101 because the claimed invention is directed to an abstract idea without significantly more. In Reference to Claim 1-3 The claim(s) recite(s) a controller and flow sensor where the controller has a function which obtains a quadratic function formula. These limitation as drafted, are processes that, under broadest reasonable interpterion cover performance of the limitation in the mind. For example, obtaining a quadratic function formula can be mentally creating a formula. The measuring and collecting of data such as flow rate just mere data gathering. This judicial exception is not integrated into a practical application because it does not impose any meaningful limits on practicing the abstract idea. The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the elements such as controller flow sensor and pump drafted as the environment where the data is being gathered. The purpose of the control calibration is to obtain a quadratic formula from data provided by the environment e.g. pump, flow sensor. Thus, the claim is not eligible. In Reference to Claim 4-6 The claim(s) recite(s) a method for obtaining a quadratic function formula. These limitation as drafted, are processes that, under broadest reasonable interpterion cover performance of the limitation in the mind. For example, obtaining a quadratic function formula can be mentally creating a formula. This judicial exception is not integrated into a practical application because it does not impose any meaningful limits on practicing the abstract idea. The claim(s) does/do not include additional elements that are sufficient to amount to significantly more than the judicial exception because the elements such as pump drafted as the environment where the data is being gathered.
