Signify North America Corporation v. Reggiani Lighting USA, Inc.

Background

Signify North America Corporation and Signify Holding B.V. sued Reggiani Lighting USA, Inc. and Reggiani S.P.A. Illuminazione for allegedly infringing five LED-related patents: U.S. Patent Nos. 7,348,604, 7,352,138, 7,766,518, 8,070,328, and 7,262,559. Reggiani asserted counterclaims for invalidity, noninfringement, patent misuse, and inequitable conduct, along with ten affirmative defenses.

Signify moved under Federal Rule of Civil Procedure 12(b)(6) to dismiss Reggiani’s third counterclaim for patent misuse and fourth counterclaim for inequitable conduct. It also moved under Rule 12(f) to strike Reggiani’s fifth and tenth affirmative defenses, which were based on the same theories.

Legal Standards

Rule 12(b)(6) tests whether a pleading states a legally sufficient claim. The court accepts well-pleaded factual allegations as true but does not accept bare legal conclusions. Because inequitable conduct is a fraud-based allegation, Federal Rule of Civil Procedure 9(b) requires the pleading to identify the specific person involved, the information allegedly withheld, when and where the conduct occurred, and how it was fraudulent. In a patent case, the pleading must also provide facts supporting a reasonable inference that a specific individual knew the information was material and withheld it with the specific intent to deceive the Patent Office.

An affirmative defense must meet the plausibility standard, although courts recognize that defendants have less time to plead defenses than plaintiffs have to plead claims. A defense that is legally insufficient or unsupported by enough facts may be stricken.

Inequitable Conduct Counterclaim

Reggiani alleged that Signify personnel withheld two patent publications during prosecution of the ’138 and ’559 patents. For the ’138 patent, Reggiani identified Claim 1 and a controller-related limitation that it said the withheld publication disclosed. For the ’559 patent, Reggiani identified relevant claims and limitations and stated where the information allegedly appeared in the withheld publication. The court said these allegations were enough at the pleading stage to identify potentially material subject matter, leaving whether the publications actually disclosed the claimed limitations for a later merits determination.

The court nevertheless dismissed the inequitable-conduct counterclaim because Reggiani did not adequately allege that the withheld information was not cumulative of information already disclosed. Reggiani acknowledged that patents from the same family had been disclosed but argued that they were buried among more than 400 references. The court concluded that, under the cited Federal Circuit authority, a reference submitted to the Patent Office generally cannot support an inequitable-conduct claim merely because it was allegedly buried among other references.

The court also found that Reggiani did not identify the responsible individual with the specificity required by Rule 9(b). For the ’138 patent, Reggiani alleged that Ihor A. Lys, Frederick M. Morgan, and/or Joseph Teja withheld the publication. The court said the allegations could plausibly suggest that Lys and Morgan knew about the publication and its materiality because they were listed as inventors, but did not adequately connect Teja to knowledge of the publication’s materiality. The use of “and/or” also left unclear whether any person who allegedly knew the information was the same person who allegedly acted with intent to deceive.

For the ’559 patent, Reggiani similarly alleged that Ajay Tripathi, Bernd Clauberg, and/or Robert J. Krause knew about and withheld a publication. The court found no sufficient detail explaining how Krause knew about the publication or its materiality. It also rejected allegations directed at Signify generally rather than at a particular individual. The court therefore held that Reggiani had not properly pleaded inequitable conduct concerning either patent.

Patent Misuse Counterclaim

Patent misuse is a court-created defense that prevents a patent holder from using a patent to obtain a monopoly beyond the patent’s legal scope. Reggiani alleged that Signify filed the infringement lawsuit knowing that the patents were likely invalid or that Reggiani’s products could not infringe, and that Signify was using the lawsuit and its broader licensing activities to stifle competition and obtain excessive licensing fees.

The court rejected this theory. It explained that patent misuse generally requires an improper expansion of the patent’s physical or temporal scope with an anticompetitive effect. Certain conduct, such as tying an unpatented product to a patented product or extending a patent beyond its expiration, may constitute misuse. But the court found no allegations of those types of conduct here. It also found no allegation that the current lawsuit concerned subject matter outside the patent claims’ scope.

Relying on Federal Circuit precedent, the court held that alleged bad-faith enforcement alone does not create a patent-misuse claim. The fact that Signify had settled other lawsuits did not show that this lawsuit was brought in bad faith, and Reggiani did not adequately allege anticompetitive effects involving the particular patents in this case. The court therefore found that Reggiani had not adequately pleaded patent misuse.

Affirmative Defenses and Disposition

The court found that Reggiani’s inequitable-conduct defense largely repeated its insufficient counterclaim and did not satisfy the required pleading standard. It also found that the patent-misuse defense was stated in only a conclusory sentence asserting that Signify was barred from relief and that the patents were unenforceable. The court declined to permit discovery as a way to search for facts that might support the defenses.

The court granted without prejudice Signify’s motion to dismiss Reggiani’s third and fourth counterclaims and to strike Reggiani’s fifth and tenth affirmative defenses. Requests for oral argument were denied as moot, and the clerk was directed to terminate the motion. This order addressed the challenged counterclaims and defenses; it did not decide Signify’s underlying patent-infringement claims.
