Roche Palo Alto & Allergan v Apotex
(9-Jul-2008)

The Federal Circuit maintained its record of never affirming a finding of non-infringement under the Reverse Doctrine of Equivalents. In this case, the Court held that relying solely on an expert opinion to establish “principle” of the claimed invention was insufficient to establish a prima facie case under the doctrine. In addition, the Court held that when the ingredients and concentrations of two formulations are both within the scope of the allegedly infringed claims, the two formulations are “essentially the same” for the purpose of evaluating claim preclusion, regardless of a possible difference in mechanisms of action in two formulations. The Court also confirmed that Claim preclusion was not limited by a “change of law” or fairness exception.

This is an action brought under the Declaratory Judgment Act, 28 U.S.C. §§ 2201, 2202, and the provision of the Hatch-Waxman Act establishing civil actions for patent certainty, 21 U.S.C. § 355(j)(5)(C). Plaintiff-Appellant Caraco Pharmaceutical Laboratories, Ltd. (“Caraco”) appeals a decision of the United States District Court for the Eastern District of Michigan dismissing its declaratory judgment action for noninfringement against Defendants-Appellees Forest Laboratories, Inc., et al., (“Forest”). Caraco’s action was dismissed for lack of Article III jurisdiction on the grounds that it had been rendered moot when Forest unilaterally granted Caraco a covenant not to sue for infringement of the patent-in-suit, U.S. Patent No. 6,916,941. However, in the context of the Hatch-Waxman framework, Forest’s covenant not to sue did not eliminate the controversy between the parties. Accordingly, we hold that Caraco’s declaratory judgment action presents a continuing Article III controversy, and reverse and remand for further proceedings. More...

Purdue Pharma L.P., et al. v. Endo Pharmaceuticals, Inc., et al.

When an inventor uses the terminology it has been surprisingly found and there is nothing surprisingly, but only obvious that follows, the patent is invalid or non-patentable. For eg. any person skilled in the art would understand and appreciate that there is nothing surprising about a different crystalline form which itself is admittedly stated as a mixture of a, and other crystalline as well as amorphous forms, is evidently attempting to obtain the grant of the patent wrongfully through unsubstantiated claims of surprisingly finding of nonexistent novelty. This also is a clear misconduct on the part of the applicant to wrongfully obtain the patent. More...

Aventis Pharma & King Pharma v. Lupin LTD

This case relates to Ramipril (Altace). Aventis Pharma & King Pharmaceuticals had sued Lupin for infringing US Patent 5,061,722 (the 722 patent) under the doctrine of equivalents. The District court held that the claims of 722 patent were not invalid. Lupin appealed from these decisions. Aventis cross-appealed for rejection of willful infringement by District court. The Appeals Court, CAFC, found the claims of Aventis's 722 patent obvious over prior art. Merck had originally patented Enalapril and Aventis developed a derivative called Ramipril. The 5(S) stereoisomer of Ramipril in a form substantially free of other isomers was held obvious and hence, claims 1 and 2 were held invalid under under 35 U.S.C. 103 over the SCH 31925 mixture, the 944 patent, and the Enalapril references in the prior art.

KSR International Co. vs. Teleflex INC.

When the obviousness of the claim is apparent in light of factors such as, content of the prior art, scope of the patent claim and the level of ordinary skill in the art, summary judgment of invalidity is appropriate. The invalidity judgment of obviousness by the District Court is upheld by the Supreme Court and the Court of Appeals (FC) decision in a narrow rigid manner inconsistent with Sec 103 of 35 USC is reversed. This landmark Judgment further tightens the obviousness criteria in Us Jurisprudence More...

Frazer et al v. Schlegel, et al
(VEXATIOUS PATENT PRIORITY ISSUES,28-Jun-2007)

The most frequently asked question is about 'Priorities'. If a prior application is published later granted later or a later application is granted earlier, who will infringe whom? While in the Pre-TRIPs regime the National filings used to receive favorable treatment, in the Post-TRIPs regime, priority from overseas filings (including PCT) receive respect and due recognition even in countries like USA, where "First to Invent" over "First to File" prevails. In the following Judgment these issues have been analyzed and the decision of the Board of Patent Appeals of USPTO was reversed by the USCA for the Federal Circuit granting priority to the earlier overseas filing.
