Addressing the issue of pleading requirements for patent infringement cases, the US Court of Appeals for the Federal Circuit clarified that patentees need not prove their case at the pleading stage on an element-by-element basis but can plead themselves out of court by presenting facts that are inconsistent with their infringement claims. Bot M8 LLC v. Sony Corp. of Am., Case No. 20-2218 (Fed. Cir. July 13, 2021) (O’Malley, J.)

Bot M8 filed suit against Sony and alleged that Sony’s PlayStation 4 and PlayStation network infringed Bot M8’s asserted patents, which are all generally directed to casino, arcade and video games. The asserted patents describe an “authentication mechanism to verify that a game program has not been manipulated,” a “gaming machine [that stores] gaming information and a mutual authentication program on the same medium,” a “gaming device with a fault inspection system,” and a “gaming machine that changes future game conditions based on players’ prior game results.”

The district court sua sponte instructed Bot M8 to file an amended complaint, “specifying ‘every element of every claim that [Bot M8] say[s] is infringed’” and to reverse engineer Sony’s products to prove its case. Bot M8 did not challenge the district court’s order and agreed to file claim charts. Following Bot M8’s service of the first amended complaint, Sony filed a motion to dismiss, which the district court granted. On an unrelated patent, both parties filed summary judgment motions. The district court entered final judgment in favor of Sony, and Bot M8 subsequently appealed both the dismissals and the grant of summary judgment.

On appeal, the Federal Circuit emphasized that “patentees need not prove their case at the pleading stage” and thus found that the district court had erred by misapplying Iqbal and Twombly. Apparently exasperated by the need to reiterate the proper pleading standard, the Court emphasized that “[a] plaintiff is not required to plead infringement on an element-by-element basis.”

While reaffirming a standard favorable to patentees, the Federal Circuit explained that for a complaint to pass muster under Iqbal and Twombly, it still must provide sufficient factual allegations to “articulate why it is plausible that the accused product infringes the patent claim.” Thus, “a patentee may subject its claims to early dismissal by pleading facts that are inconsistent with the requirements of its claims.” The Court explained that Bot M8’s allegations conflicted with claim 1 of Bot M8’s patent. Whereas that claim required a motherboard separate from the authentication and game programs, Bot M8’s claim charts expressly alleged that “[t]he authentication program for the PlayStation 4 hard drive, operating system, and games is stored on PlayStation 4 . . . Serial Flash Memory” and that “[t]he PlayStation 4 motherboard contains flash memory.” According to the Court, it was “not even possible, much less plausible” for Bot M8 to prevail because of this inconsistency between Bot M8’s allegations and its patent with respect to the location of the authentication and game programs relative to the motherboard. By pleading “too much rather than too little,” Bot M8 “essentially pleaded itself out of court.”

Practice Note: Patentees seeking to enforce their patent rights against alleged infringers should focus on the quality of their allegations, rather than the quantity. Failing to do so may be the reason patentees find their infringement claim dismissed. A complaint should contain just the right amount of factual allegations—not too much, not too little.
