Game and Technology Co., Ltd. v. Activision Blizzard Inc.
926 F.3d 1370
Fed. Cir.2019Background
- GAT owns U.S. Patent No. 8,253,743 (the ’743 patent) claiming a method/system to create a “gamvatar” by combining an avatar with game-item functions via multiple "layers." Claim 1 recites an avatar with multiple layers for displaying avatar functions or performing game item functions, and that game item functions are "exhausted" when used in gameplay.
- Activision Blizzard and Riot (collectively "Activision") petitioned for IPR challenging claims 1–11 as obvious. The PTAB issued a final written decision finding the challenged claims obvious over the Diablo II Manual alone and in combination with Rogers.
- The Diablo II Manual (a videogame manual) discloses customizable characters that equip/display items (weapons, armor, potions), an inventory UI with slots/boxes, and online play via Battle.net (distinct from single-player game instances).
- Rogers (a published patent application) discloses customizable avatars using graphical layering techniques and a graphics subsystem that layers clothing/accessories to avoid visual bleeding.
- On appeal GAT challenged (1) the PTAB’s constructions of “gamvatar” and “layers,” and (2) the PTAB’s conclusion that the claims are obvious over the prior art. The Federal Circuit affirmed.
Issues
| Issue | Plaintiff's Argument (GAT) | Defendant's Argument (Activision / PTAB) | Held |
|---|---|---|---|
| Construction of “gamvatar” | "Gamvatar" requires concurrent use both in-game and on a website (narrower construction). | The spec/claims define a gamvatar as an avatar combined with game-item functions; not limited to concurrent online/ in-game use (broader). | PTAB construction affirmed: "gamvatar" = conventional avatar combined with game-item functions (not limited to concurrent use online and in-game). |
| Construction of “layers” | "Layers" should mean constructs that display graphical objects on the avatar (i.e., displayed on the avatar). | "Layers" encompasses graphics regions for displaying graphical objects and constructs for holding graphics; need not be displayed on the avatar itself (background or separate regions qualify). | PTAB construction affirmed: "layers" includes graphical regions/constructs and does not require display on the avatar image. |
| Whether Diablo II Manual (alone) anticipates/teaches claimed features | Diablo II does not disclose a gamvatar with layers for performing game item functions as claimed. | Diablo II discloses avatars, inventory slots/boxes (multiple graphical regions), use of items that perform functions, and Battle.net as a distinct online environment—supporting claimed elements. | Substantial evidence supports PTAB: Diablo II Manual discloses relevant avatar, layered graphical regions, and online (Battle.net) usage; supports obviousness. |
| Obviousness over Diablo II ± Rogers | Claims are nonobvious because prior art does not disclose required combination of layered game-item functions and online-avatar aspects. | Claims would have been obvious to a PHOSITA from Diablo II alone or combined with Rogers (layering techniques from Rogers). | Affirmed: PTAB’s obviousness findings sustained; claims obvious over Diablo II alone or with Rogers; single reference can render claim obvious if modification is routine. |
