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 .
Examiner Note
The features of claim 24 referring to “a control signal to automatically change an operational mode of the battery if the determined internal temperature exceeds the prescribed threshold” would be sufficient in overcoming the rejection under 35 USC 101 below if it were amended into the independent claim and also not listed as an ‘option’ feature.
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 1-10 and 18-27 are rejected under 35 U.S.C. § 101 because the claimed invention is directed to a judicial exception (i.e., an abstract idea) without “significantly more.” Claims 1-10 and 18-27 are directed to determining a heat generation rate, a temperature change of the battery and an internal temperature of the battery, which is considered an abstract idea. Further, the claim(s) as a whole, when examined on a limitation-by-limitation basis and in ordered combination do not include an inventive concept.
Step 1 – Statutory Categories
As indicated in the preamble of the claims, the examiner finds the claims are directed to a process, machine, or article of manufacture.
Step 2A – Prong One - Abstract Idea Analysis
Exemplary claim 1 (and similarly claims 25 and 26) recites the following abstract concepts, in italics below, which are found to include an “abstract idea”:
A computer-implemented method for determining an internal temperature of a battery, the method comprising:
obtaining an initial temperature condition of the battery indicative of battery temperature at an initial time;
receiving current data indicative of electrical current in the battery at a given time after the initial time, and receiving ambient temperature data indicative of ambient temperature associated with the battery at the given time;
determining a heat generation rate in the battery based on an internal resistance of the battery and on the received current data;
determining a temperature change of the battery at the given time from the initial time, the temperature change being determined based on the obtained initial temperature condition and the determined heat generation rate; and,
determining the internal temperature of the battery based on the determined temperature change and the received ambient temperature data.
The claim features in italics above as drafted, under its broadest reasonable interpretation, are mental processes performed by generic computer components. That is, other than reciting “a battery” and “obtaining an initial temperature condition of the battery indicative of battery temperature at an initial time; receiving current data indicative of electrical current in the battery at a given time after the initial time, and receiving ambient temperature data indicative of ambient temperature associated with the battery at the given time” (none of these features actually recite the hardware/additional elements used to obtain or receive such data, but it is assumed that hardware is need in order to obtain/receive this specific information) nothing in the claim element precludes the step from practically being performed in the mind. For example, but for the “obtaining” and “receiving” language, “determining a heat generation rate in the battery based on an internal resistance of the battery and on the received current data; determining a temperature change of the battery at the given time from the initial time, the temperature change being determined based on the obtained initial temperature condition and the determined heat generation rate; and, determining the internal temperature of the battery based on the determined temperature change and the received ambient temperature data” in the context of this claim encompasses mental processes. If the claim limitations, under its broadest reasonable interpretation, covers steps which could be performed in the human mind including an observation, evaluation, judgement of opinion but for the recitation of generic computer components, then it falls within the “mental process” grouping of abstract ideas. Accordingly, the claim recites an abstract idea.
Step 2A – Prong Two - Abstract Idea Analysis
This judicial exception is not integrated into a practical application. In particular, the claims only recite a few additional elements – “a battery”, “obtaining an initial temperature condition of the battery indicative of battery temperature at an initial time; receiving current data indicative of electrical current in the battery at a given time after the initial time, and receiving ambient temperature data indicative of ambient temperature associated with the battery at the given time” (again, none of these features actually recite the hardware/additional elements used to obtain or receive such data, but it is assumed that hardware is need in order to obtain/receive this specific information), a UPS system (claim 23) and one or more processors (claims 25 and 26) and a device (claim 27). The additional elements are recited at a high-level of generality (i.e., as a generic processor performing generic computer functions) such that it amounts no more than mere data gathering, which is a form of insignificant extra-solution activity (MPEP 2106.05(g), i.e. the sensors used to obtain the temperature of the battery, electric current and ambient temperature are generically functioning as they were designed). Accordingly, these additional elements do not integrate the abstract idea into a practical application because they do not impose any meaningful limits on practicing the abstract idea. The claim is directed to an abstract idea.
Step 2B - Significantly More Analysis
The claim does not include additional elements that are sufficient to amount to
significantly more than the judicial exception. As discussed above with respect to integration of the abstract idea into a practical application, the additional elements of “obtaining an initial temperature condition of the battery indicative of battery temperature at an initial time; receiving current data indicative of electrical current in the battery at a given time after the initial time, and receiving ambient temperature data indicative of ambient temperature associated with the battery at the given time”, a UPS system, one or more processors and device amount to no more than mere insignificant extra-solution activity. Mere insignificant extra-solution activity cannot provide an inventive concept. For these reasons, there is no inventive concept. The claim is not patent eligible.

Because the experimental methods in steps 1) and 2) can generally only obtain the temperature field distribution on the battery surface, and there is a large temperature difference between the battery interior and the battery surface, the battery surface temperature cannot truly reflect the temperature situation inside the battery. However, simulation analysis can more accurately obtain the temperature field inside the battery”).
