Amgen Inc. v. Sandoz Inc.

Citation: 295 F. Supp. 3d 1062Docket: Case No. 14-cv-04741-RS; Case No. 16-cv-02581-RS

Court: District Court, N.D. California; December 18, 2017; Federal District Court

Narrative Opinion Summary

This case involves a patent infringement dispute between two competitors in the biopharmaceutical industry concerning U.S. Patent No. 8,940,878, which pertains to protein purification processes. The plaintiffs, Amgen Inc. and Amgen Manufacturing, Limited, alleged that the defendants, collectively referred to as Sandoz, infringed on claim 7 of the '878 patent with their AEX purification step. Sandoz sought summary judgment on noninfringement, asserting that their process did not meet the patent's requirements, particularly the sequential steps of washing and eluting using distinct solutions. The court granted Sandoz's motion, finding no literal infringement, as the AEX step involved only one step and one solution. Amgen's motion under Rule 56(d) to defer the ruling based on anticipated modifications to Sandoz's process was denied, as the court determined these changes would not alter the infringement analysis. Additionally, the court ruled out the doctrine of equivalents, citing significant differences between the patented method and Sandoz's process, which precluded equivalency. As a result, the damages arguments were deemed moot. The court instructed Sandoz to submit a proposed final judgment and addressed several motions concerning the handling of materials and submissions in the case.

Legal Issues Addressed

Doctrine of Equivalents in Patent Infringement

Application: Differences between Sandoz's AEX step and the claimed method were substantial, negating claims of equivalency and supporting noninfringement.

Reasoning: In this case, the differences between the claimed method of the '878 patent and the accused AEX step are significant.

Literal Infringement Requirement

Application: The court found no literal infringement as Sandoz's process did not perform the sequential steps required by the patent claim.

Reasoning: Sandoz's accused AEX step involves only one step and one solution. Specifically, Sandoz asserts that four elements of claim 7 are not met.

Rule 56(d) Motion for Continuance

Application: Amgen's request to defer the ruling based on anticipated process modifications by Sandoz was denied as the court found these changes irrelevant to the noninfringement determination.

Reasoning: The court finds that the specific parameters Amgen wishes to discover are not relevant to the noninfringement determination since the fundamental differences between the claimed method and Sandoz's process remain unchanged.

Standing to Claim Damages in Patent Infringement

Application: Sandoz argued that AML lacked standing for damages as it was neither an owner nor exclusive licensee of the patent; however, the damages issue was deemed moot due to noninfringement.

Reasoning: Sandoz seeks summary judgment on noninfringement and damages, arguing that: (1) AML lacks standing as it is neither an owner nor exclusive licensee of the '878 patent.

Summary Judgment on Noninfringement

Application: Sandoz successfully demonstrated that its accused AEX step did not meet the elements of the '878 patent, leading to summary judgment on noninfringement.

Reasoning: The argument that the eluting step must occur after the washing step alone is sufficient to conclude that Sandoz's AEX step does not literally infringe the '878 patent.
