Patent Infringement Opinion

Infringement opinion overview:

  • To infringe a patent claim, the subject must have every element recited in the claim or its equivalent.

  • An infringement opinion requires an interpretation of the patent claims, which in turn requires an examination of the USPTO file of the application from which the patent issued and all prior art cited therein.

  • A patent infringement opinion requires a comprehensive evaluation of the accused (or about to be accused) product or process.

  • A patent infringement opinion might require evaluations of alternatives to the the client's current product or process proposals.

  • A patent infringement opinion might lead to patent validity issues.

  • A patent infringement opinion obtained by a third-party is commonly called a 'right to use' letter or opinion.

  • Is a patent infringement opinion worth the costs?  This is always a business decision.
