ALAN RICHARD SILVERSTEIN, Connolly Gallagher LLP, Wilmington, DE, for defendant-appellee Mach7 Technolo- gies, Inc. ______________________

Before MOORE, Chief Judge, REYNA and HUGHES, Circuit Judges. REYNA, Circuit Judge. AI Visualize, Inc. sued Nuance Communications, Inc. and Mach7 Technologies, Inc. in the District of Delaware for patent infringement. Nuance and Mach7 moved to dis- miss under Federal Rule of Civil Procedure 12(b)(6) for fail- ure to state a claim. They argued that the asserted patent claims were directed to patent-ineligible subject matter and therefore invalid under 35 U.S.C. § 101. The district court granted the motion, finding the asserted claims were directed to an abstract idea and failed to provide an in- ventive step that transformed that abstract idea into a pa- tent-eligible invention. The district court entered judgment and dismissed AI Visualize’s case. For the rea- sons below, we affirm. BACKGROUND A. The Asserted Patents The four patents at issue are U.S. Patent Nos. 8,701,167 (’167 patent), 9,106,609 (’609 patent), 9,438,667 (’667 patent), and 10,930,397 (’397 patent). They are part of the same patent family and share substantially the same specification. 1 The field of the asserted patents generally relates to visualization of medical scans. Each patent is titled “Method and system for fast access to advanced vis- ualization of medical scans using a dedicated web portal.”

1 We refer to the ’609 patent specification for all four asserted patents. Case: 22-2109 Document: 61 Page: 3 Filed: 04/04/2024

AI VISUALIZE, INC. v. NUANCE COMMUNICATIONS, INC. 3

According to the patents, medical imaging systems like magnetic resonance imaging (MRI) scans typically create a collection of two-dimensional cross-section images of a pa- tient’s body or organ. ’609 patent, 1:27–32. These images are often stored together at a centralized server as a three- dimensional collection of data representing the scanned area, referred to as a “volume visualization dataset” or “VVD”. Id. at 1:30–35. At the time of the invention, “[t]ech- nology exist[ed]” to use these VVDs “to present rich[] three- dimensional (3D) views from existing two-dimensional (2D) scans that may lead to better diagnosis and prognosis.” Id. at 1:22–25; see also id. at 1:35–46. But the inventors recognized complications with at- tempts to view portions of these large VVDs at a client com- puter. To look at a three-dimensional view, “either the user’s computer or a dedicated server need[ed] to be pow- erful enough to support [the] processing power and the 2D scans need[ed] to be directly available to the user’s com- puter via a high speed communication link.” Id. at 1:49–53. The patents thus explain that “[t]he present invention overcomes this limitation by teaching a method and system of a common and centralized infrastructure, for receiving, storing, processing and viewing large medical scans via a low-bandwidth web portal.” Id. at 1:58–62. They describe systems and methods for users to review three-dimensional (or higher dimension) “virtual views” of a VVD on a com- puter connected to the internet without having to transmit or locally store the entire VVD. Id. at 2:52–57. At issue in this appeal are claims 1, 6, 7, 9, 12, and 13 of the ’167 patent; claims 1, 4, 6–9, 19, 20, 22, 25, and 26 of the ’609 patent; claims 1–3, 8, 9, 11, 14, and 15 of the ’667 patent; and claims 1–3, 11–14, and 16–18 of the ’397 pa- tent. The parties agree that for purposes of a 35 U.S.C. § 101 analysis, these asserted claims can be sorted into three groups, with each group represented by one claim of the ’609 patent. See Berkheimer v. HP Inc., 881 F.3d 1360, 1365 (Fed. Cir. 2018) (holding that claims may be treated Case: 22-2109 Document: 61 Page: 4 Filed: 04/04/2024

as “representative” in a § 101 inquiry if a patentee makes no “meaningful argument for the distinctive significance of any claim limitations not found in the representative claim”). The claims in group 1 involve systems where a web ap- plication determines which frames of a virtual view, if any, are already stored locally on a user’s device; directs the server to create any necessary, additional frames for trans- mission to the user’s device; compiles at the user’s device the locally-stored and newly-received frames to create the desired virtual view; and displays the user’s requested vir- tual view. ’609 patent, claim 1. The parties agree that claim 1 of the ’609 patent is representative of the group 1 claims. 2 Claim 1 recites: 1. A system for viewing at a client device at a remote location a series of three-di- mensional virtual views over the Internet of a volume visualization dataset contained on at least one centralized database com- prising: at least one transmitter for accepting vol- ume visualization dataset from remote lo- cation and transmitting it securely to the centralized database; at least one central data storage medium containing the volume visualization da- taset; a plurality of servers in communication with the at least one centralized database

2 The group 1 claims are: claims 1, 4, and 6–9 of the ’609 patent; claim 1 of the ’167 patent; claims 1–3 of the ’667 patent; and claims 1–3, 11–14, and 16–18 of the ’397 patent. Case: 22-2109 Document: 61 Page: 5 Filed: 04/04/2024
