Bot M8 LLC v. Sony Corporation of America
4 F.4th 1342
Fed. Cir.2021Background
- Bot M8 sued Sony asserting five patents at issue on appeal (U.S. Pat. Nos. 8,078,540; 8,095,990; 7,664,988; 8,112,670; 7,338,363) related to gaming machines and authentication/boot/fault-inspection and game-parameter renewal features.
- Case transferred to N.D. Cal.; at a case-management conference the district court asked Bot M8 to file an amended complaint with element-by-element detail and claim charts; Bot M8 filed a 223‑page FAC.
- The district court dismissed infringement claims as to the '540, '990, '988, and '670 patents for failure to plead plausibly, denied Bot M8 leave to file a second amended complaint after Bot M8 sought to add evidence obtained by reverse‑engineering (jailbreaking) the PS4, and granted summary judgment that claim 1 of the '363 patent is patent‑ineligible under § 101.
- Bot M8 argued it could not reverse engineer earlier because of the DMCA and other anti‑hacking constraints; the district court applied Rule 16 (good‑cause/diligence) and found Bot M8 untimely and not diligent.
- On appeal, the Federal Circuit affirmed the court’s directions to amend, affirmed dismissal as to the '540 and '990 patents, reversed dismissal as to the '988 and '670 patents (finding plausible allegations), affirmed denial of leave to amend under Rule 16, affirmed § 101 invalidity of the '363 patent, and remanded limited claims ('988, '670) for further proceedings.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| District court sua sponte directing Bot M8 to file an amended complaint at CMC | Court improperly forced re‑pleading and demanded source code | Court gave notice and option; Ninth Circuit permits courts to note inadequacy and allow response | No abuse of discretion; direction permissible and Bot M8 voluntarily amended |
| Adequacy of FAC re: '540 patent (board memory location requirement) | FAC contained detailed claim charts and multiple alleged storage components (HDD, Blu‑ray, servers, flash) | Allegations contradictory and pleaded authentication program as located on PS4 motherboard (inconsistent with claim) | Affirmed dismissal — allegations inconsistent/implausible |
| Adequacy of FAC re: '990 patent (mutual authentication stored together) | FAC identified multiple storage media supporting the limitation | Allegations were conclusory, tracked claim language, and failed to show gaming info and mutual auth program are stored together | Affirmed dismissal — conclusory, not plausible |
| Adequacy of FAC re: '988 and '670 patents (fault inspection completes before game start) | FAC alleges multiple express statements and boot‑time error messages supporting that inspection completes before game start | Sony: allegations merely track claim language and don't prove completion before start | Reversed dismissal — FAC plausibly alleges completion before game start; remanded |
| Denial of leave to file second amended complaint (timeliness/diligence under Rule 16) | Motion timely filed after permission to jailbreak and based on new evidence; should be reviewed under Rule 15 liberal standard | Motion was untimely, Bot M8 had earlier represented it had reverse‑engineered the PS4 and failed to show diligence; Rule 16 governs post‑deadline amendments | Affirmed — district court did not abuse discretion in denying leave under Rule 16 |
| Patent eligibility of claim 1 of '363 under 35 U.S.C. § 101 | Claim 1 describes concrete multiplayer‑game mechanisms and inventive improvements | Claim is directed to an abstract idea (adjusting game difficulty based on aggregate past results) and uses generic computer components without an inventive concept | Affirmed — claim 1 is ineligible under § 101 (Alice two‑step applied) |
