Benefits of the total Invalidity defense service

Envision IP provides US-based patent research services that have the depth and domain expertise of subject-matter experts. For each invalidity search assessment, we start by understanding client goals and reasons for conducting the search. We also discuss the claim scope at issue. Oftentimes, our analysts will manually review the file history and prior litigation to understand potential claim interpretation.

Benefits include:

  • Centralized multiple, parallel searchers and search strategies that provide broad and comprehensive coverage efficiently.
  • Optional fixed annual cost to include for all invalidity assessments projected for the year.
  • Up-front cost, all inclusive. No hourly billing, overages, or database access charges.
  • Can be used by your in-house team, or outside counsel.
  • No fees to expedite a search, with standard delivery in under two weeks. When necessary, results can be provided in as little as 24 hours.
  • Upon request, we provide claim scope guidance for the search by reviewing of the prosecution history and any prior/current litigation claim construction.

assessing patent validity is important for defendants and patent owners alike.

New case law, continued growth in patent grants, and sustained assertion activity by non-practicing entities have resulted in a surge of patent infringement cases. Additionally, more than 2,000 challenges have been filed before the Patent Appeal & Trial Board (PTAB).

To address the needs of businesses that must routinely assess patent validity – both patent owners and defendants – Envision IP offers a unique, subscription-based invalidity search service.

multiple search strategies; worldwide prior art coverage

Envision IP's approach permits your organization to interface with a single firm on high-stakes litigation, instead of having to retain multiple third-parties to conduct parallel searches.  We assign a dedicated three-member team, which includes at least one former USPTO examiner and a patent attorney, to conduct your invalidity assessment.

Envision IP utilizes powerful subscription-based tools to search worldwide patent databases and non-patent literature sources, including numerous technical journals, university repositories, and scientific research databases.  We have access to nearly 500,000 non-patent literature sources, including journals, conference proceedings, educational materials, standards documents, and magazines, and our in-house print and online repository.  

In addition, we access patent databases from 44 different countries, with the ability to search non-English language patent data from various Asia-Pacific, European, and South American jurisdictions.
