Motion detection system found to be ineligible patent subject matter
| February 18, 2021
iLife Technologies v. Nintendo
January 13, 2021
Moore, Reyna and Chen. Opinion by Moore.
Summary:
iLife sued Nintendo for infringing its patent to a motion detection system. Claim 1 of the patent recites a motion detection system that evaluates relative movement of a body based on both dynamic and static acceleration, and a processor that determines whether body movement is within environmental tolerance and generates tolerance indica, and then the system transmits the tolerance indica. In granting Nintendo’s motion for JMOL, the district court held that claim 1 of iLife’s patent is directed to patent ineligible subject matter under § 101. The CAFC affirmed the district court stating that claim 1 of the patent is directed to the abstract idea of “gathering, processing, and transmitting information” and no other elements of claim 1 transform the nature of the claim into patent-eligible subject matter.
Details:
The patent at issue in this case is U.S. Patent No. 6,864,796 to a motion detection system owned by iLife. iLife sued Nintendo for infringement of claim 1 of the ‘796 patent. Claim 1 of the ‘796 patent is provided:
1. A system within a communications device capable of evaluating movement of a body relative to an environment, said system comprising:
a sensor, associable with said body, that senses dynamic and static accelerative phenomena of said body, and
a processor, associated with said sensor, that processes said sensed dynamic and static accelerative phenomena as a function of at least one accelerative event characteristic to thereby determine whether said evaluated body movement is within environmental tolerance
wherein said processor generates tolerance indicia in response to said determination; and
wherein said communication device transmits said tolerance indicia.
Nintendo moved for summary judgment arguing that claim 1 is directed to patent ineligible subject matter. The district court declined to decide the eligibility issue on summary judgment and the case proceeded to a jury trial. After a jury verdict in favor of iLife, Nintendo moved for a judgment as a matter of law (JMOL) again arguing patent ineligibility. The district court granted Nintendo’s motion for JMOL holding that claim 1 is directed to ineligible subject matter.
The CAFC followed the two-step test under Alice for determining patent eligibility.
1. Determine whether the claims at issue are directed to a patent-ineligible concept such as laws of nature, natural phenomena, or abstract ideas. If so, proceed to step 2.
2. Examine the elements of each claim both individually and as an ordered combination to determine whether the claim contains an inventive concept sufficient to transform the nature of the claims into a patent-eligible application. If the claim elements involve well-understood, routine and conventional activity they do not constitute an inventive concept.
Under step one, iLife argued that claim 1 is not directed to an abstract idea because claim 1 recites “a physical system that incorporates sensors and improved techniques for using raw sensor data” in attempt to analogize with Thales Visionix Inc. v. United States, 850 F.3d 1343 (Fed. Cir. 2017) and Cardio-Net, LLC v. InfoBionic, Inc., 955 F.3d 1358 (Fed. Cir. 2020). However, the CAFC distinguished Thales because in Thales, “the claims recited a particular configuration of inertial sensors and a specific choice of reference frame in order to more accurately calculate position and orientation of an object on a moving platform.” The court in Thales held that the claims were directed to an unconventional configuration of sensors.”
The CAFC also distinguished Cardio-Net because the claims in that case were “focused on a specific means or method that improved cardiac monitoring technology, improving the detection of, and allowing more reliable and immediate treatment of atrial fibrillation and atrial flutter.” The CAFC started that claim 1 of the ‘796 patent “is not focused on a specific means or method to improve motion sensor systems, nor is it directed to a specific physical configuration of sensors.” Thus, the CAFC concluded that claim 1 is directed to the abstract idea of “gathering, processing, and transmitting information.”
Under step two, the CAFC stated that “[a]side from the abstract idea, the claim recites only generic computer components, including a sensor, a processor, and a communication device.” The CAFC also reviewed the specification finding that these elements are all generic. iLife attempted to argue that “configuring an acceleration-based sensor and processor to detect and distinguish body movement as a function of both dynamic and static acceleration is an inventive concept.” But the CAFC pointed out that the specification describes that sensors that measure both static and dynamic acceleration were known. The CAFC further stated that “claim 1 does not recite any unconventional means or method for configuring or processing that information to distinguish body movement based on dynamic and static acceleration. Thus, the CAFC concluded that merely sensing and processing static and dynamic acceleration information using generic components “does not transform the nature of claim 1 into patent eligible subject matter.”
Comments
When drafting patent applications, make sure to include specific details for performing particular functions and/or specific configurations. Claims including details about performing functions or about specific configurations will have a better chance to survive step one of the Alice test for patent eligibility. The specification should also include descriptions of why the specific functions or configurations provide improvements over the prior art to be able to show that the claims provide an “inventive concept” under step two of Alice.
