Texas Court Upholds Patent Infringement Verdict Against Natera in Ravgen Case

In a notable decision within the realm of intellectual property law, a Texas federal judge has affirmed a jury’s verdict against genetic testing company Natera Inc., confirming literal infringement of a patent held by Ravgen Inc. This decision, while reinforcing the jury’s determination, did not accept all aspects of Ravgen’s claims, specifically rejecting the expert testimony that aimed to demonstrate infringement under the doctrine of equivalents. This legal nuance underscores the complexities inherent in patent litigation, where the boundaries between literal infringement and equivalent infringement remain critically significant.

The jury initially awarded Ravgen Inc. a $57 million judgment, signifying a substantial financial implication for Natera. This judgment is rooted in the jury’s interpretation of patent infringement, focusing on the literal text of the patent claims. Such decisions are critical as they guide the actions and strategies of technology companies navigating the intricate landscape of patent rights [Law360](https://www.law360.com/ip/articles/2443636?utm_source=rss&utm_medium=rss&utm_campaign=section).

Natera’s defense, while unsuccessful in disproving literal infringement, managed to cast doubt on the applicability of the doctrine of equivalents. This doctrine allows for a broader interpretation of patent claims, often invoked when the literal language of the patent does not explicitly cover the alleged infringer’s actions but is deemed to capture the essence of the patented invention. In this case, however, the judge found Ravgen’s evidence insufficient to support such a claim, emphasizing the high standard required to prove infringement under this legal theory.

While the outcome marks a victory for Ravgen, it also illustrates the ongoing challenges faced by companies in protecting intellectual property. The ruling not only impacts the involved parties but also resonates throughout the industry, highlighting the importance of clearly defined patent claims and robust evidence when asserting rights under both literal infringement and the doctrine of equivalents.

This case adds to the broader dialogue on patent enforcement, an area that continues to evolve with technological advancements, ensuring that patent holders and practitioners alike must continuously adapt to the shifting legal landscape. As companies innovate, courts remain a central battleground for resolving disputes over the ownership and use of technological advancements. The decision serves as a reminder of the critical role that precise legal language and factual evidence play in determining the outcome of complex patent disputes.
