Case Study 7 – Comparative analysis of tablets with different coatings

The Challenge:

The case required the analysis of tablets coated with an enteric polymer, both with and without sub-coats. Infringement was based on whether the sub-coat effectively separated the drug substance from the enteric coating material.

The Acumen Approach:

The Acumen expert witness team came together to provide:

  • Comprehensive literature review.
  • Analysis of prior art regarding the role of coating materials and methods to examine the accused process from the perspective of the patents en suit.
  • Sound technical arguments and court testimony to defend the client against untrue infringement allegations.
The Result:

Case was settled in favor of the client.
