Sending Infringement Notice Letters May Create Personal Jurisdiction

The United States Court of Appeals for the Federal Circuit recently reversed a district court’s grant of motion to dismiss a declaratory judge action against Plano Encryption Technologies LLC (PET). The district court, which is situated in the Northern District of Texas, held that PET’s contacts with the Northern district did not subject it to personal jurisdiction and venue was thus improper. On appeal, the Federal Circuit reversed and remanded for further proceedings… While personal jurisdiction and venue are fact-dependent inquiries, sending patent enforcement letters to a recipient located and doing business in a forum can be enough to establish personal jurisdiction over the sending party in the forum such that venue is proper in the forum. Such a finding may be particularly true when the sending party’s “sole business is to enforce its intellectual property.”

CAFC Refuses to Find Post-URAA Patent to be Invalidating Reference Against Pre-URAA Patent

The Federal Circuit recently reversed a decision by the United States District Court for the District of Delaware holding that a patent filed after the Uruguay Round Agreement Act (“URAA”) is a proper obviousness-type double patenting reference against an earlier-filed, yet later-expiring, pre-URAA patent. Applying the Federal Circuit case Gilead Sciences, Inc. v. Natco Pharma Ltd., the district court invalidated the earlier-filed compound patent by asserting the later-filed method of treatment patent as a double patenting reference. The Federal Circuit reversed the decision by holding the analysis in Gilead “was limited to the context of when both patents in question are post-URAA patents.” While the Court limited the present opinion to the specific facts of this case, the Court applied pre-URAA double-patenting practices to the pre-URAA patent and reasoned that the invalidating reference “did not exist as a double patenting reference” when the pre-URAA patent issued

Defensive Collateral Estoppel Applies Only if Essentially Identical Accused Product Found Non-infringing

In its opinion, the Federal Circuit explained that defensive collateral estoppel of non-infringement applies in very limited circumstances where “a close identity exists between the relevant features of the accused device and the device previously determined to be non-infringing such that they are ‘essentially the same.’” Accused products are essentially the same where “the difference between them are merely ‘colorable’ or ‘unrelated to the limitation in the claim of the patent.’” Thus, “[i]f accused devices in a second suit remain ‘unchanged with respect to the corresponding claim limitations at issue in the first suit,’ the patentee is precluded from pursuing its infringement claims a second time.” The burden is on the proponent of claim or issue preclusion to show that the accused products are essentially the same.

CAFC: Patent Claim Directed to Concrete Assignment of Specified Functions is Patent Eligible

The Federal Circuit recently reversed the Western District of Washington’s dismissal under Rule 12(b)(6) of the Federal Rules of Civil Procedure where the district court held that the claimed subject matter was ineligible for patenting under 35 U.S.C. § 101. Specifically, the Federal Circuit, reviewing the decision de novo, concluded that the claimed method of improving security was a non-abstract computer-functionality improvement because it was done by a specific technique that departs from earlier approaches resulting in a beneficial reduction of the risk of hacking.

Federal Circuit Holds a ‘Similar Enough’ Claim Construction Doesn’t Violate the APA

In Hamilton Beach Brands v. F’Real Foods, the Federal Circuit found that under the Administrative Procedure Act, the Patent Trial and Appeal Board’s adopted claim construction in an IPR need not be identical to a construction proposed by a party so long as the construction is “similar enough” to provide notice for the parties to argue for or against the construction.
