Probatter Sports, LLC v. Sports Tutor, Inc., 680 F. App'x 972 (Fed. Cir. 2017).

Opinion

The district court in this case entered summary judgment that Sports Tutor, Inc., infringes two of ProBatter ' Sports, LLC’s, patents relating to pitching machines. Sports Tutor appeals the district court’s determination that those patents were not invalid as obvious. Because Sports Tutor did not meet its burden of *973 establishing obviousness before the district court, we affirm.

Background

ProBatter and Sports Tutor both sell programmable pitching machines meant to simulate real-life pitching situations. Pro-Batter’s mechanical pitching machine stands behind a video projection of an actual pitcher winding up and pitching. A ball thrust from the pitching machine emerges from a hole in the video screen towards a batter and/or catcher. ProBat-ter’s product synchronizes the ball release with the video so that the batter and/or catcher experience something similar to a live pitcher’s pitch. The machine can throw a wide variety of pitch, types at varying speeds and can alternate between right-handed and left-handed pitcher simulation. Major league and collegiate baseball programs have purchased ProBatter’s system.

The ProBatter system practices ProBat-ter’s U.S. Patent No. 6,182,649 and its continuation patent, U.S. Patent No. 6,546,924. These patents describe a ball-throwing machine “able to interchangeably deliver pitches of different types to different locations at different speeds with less than ten-second intervals between pitches.” ’649 patent abstract. The claimed machine is also capable of changing pitch type, speed, and delivery location “without the need to manually readjust the machine between pitches.” Id. at col. 3 11. 43-46. The patents allege that this was not possible in prior art machines because of the difficulty in quickly changing motor speed. The patents explain that the claimed machine is able to rapidly decelerate its motors by incorporating a dynamic braking mechanism.

By way of example, independent claim 27 of the ’649 patent recites:

27. A ball-throwing machine of the type having a power head including at least two coacting wheels for propelling a ball toward a batter to simulate a pitch, said power head being pivotably mounted on a base at a center pivot about which the power head may be pivoted in both a horizontal and a vertical direction, said machine including:
means for causing the power head to rotate about said center pivot to assume a predetermined horizontal position, said means for causing comprising at least one horizontal linear actuator; and
means for causing the power head to rotate about said center pivot to assume a predetermined vertical position, said means for causing comprising at least one vertical linear actuator; and
dynamic braking means for powering motors for the said eoacting wheels, said means comprising a dynamic or regenerative braking circuit.

’649 patent reexamination certificate col. 3 11.12-28.

ProBatter sued Sports Tutor in the District of Connecticut, alleging that Sports Tutor’s HomePlate machine infringed ’649 patent claims 1-12, 25-27, and 31, as well as ’924 patent claim 1. Sports Tutor then challenged the patents in a series of ex parte reexaminations, two on each patent, during which the district court stayed the litigation. In the first round of reexaminations, the examiner rejected many of the claims as obvious in view of the prior art, but the Board of Patent Appeals and Interferences reversed those rejections and allowed the claims. The Board reasoned that the dynamic braking limitation was not disclosed in any of the allegedly anticipatory references and that there was no motivation to combine the prior art ball-throwing machine references with the pri- or art dynamic braking reference, U.S. Patent No. 5,187,419 (“DeLange”), drawn generally to an electric motor. The examiner rejected Sports Tutor’s invalidity chai- *974 lenges in the second round of reexaminations and allowed the asserted claims.

Following reexamination, the district court lifted the stay and entered summary judgment of infringement, which Sports Tutor does not appeal. The district court denied motions seeking to determine validity on summary judgment and held a bench trial on that issue, after which the parties filed post-trial briefs. The court ruled that Sports Tutor did not carry its clear and convincing burden at trial or in its post-trial briefing to prove invalidity of the asserted patent claims. The district court specifically found that Sports Tutor did not satisfy its burden because it never explicitly argued for a particular combination of references or proffered a motivation to combine references. The court emphasized that it could not make factual findings on the scope and content of the prior art or the differences between the claims and the prior art because Sports Tutor failed to identify any particular prior art combinations.

Sports Tutor appeals the district court’s validity ruling, and we have jurisdiction under 28 U.S.C. § 1295(a)(1).

Discussion

I.

A patent claim is unpatentable as obvious “if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art.” 35 U.S.C. § 103. 1 “[Pjatents are presumed to be valid and overcoming this presumption requires clear and convincing evidence.” Alcon Research Ltd. v. Barr Labs., Inc., 745 F.3d 1180, 1188 (Fed. Cir. 2014) (citing 35 U.S.C. § 282; Microsoft Corp. v. i4i Ltd., 564 U.S. 91, 95, 131 S.Ct. 2238, 180 L.Ed.2d 131 (2011); Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1354 (Fed. Cir. 2010) (en banc)).

“Obviousness is a question of law, based on underlying factual determinations including: ‘the scope and content of the prior art’; ‘differences between the prior art and the claims at issue’; ‘the level of ordinary skill in the pertinent art’; and ‘[s]uch secondary considerations as commercial success, long felt but unsolved needs, failure of others, etc.’ ” Insite Vision Inc. v. Sandoz, Inc., 783 F.3d 853, 858 (Fed. Cir. 2015) (quoting Graham v. John Deere Co., 383 U.S. 1, 17, 86 S.Ct. 684, 15 L.Ed.2d 545 (1966)). “Following a bench trial on the issue of obviousness, we review the court’s ultimate legal conclusions de novo and the underlying factual findings for clear error.” Id.
