Q.
Patent search: A comparative table of databases

What are the major patent databases and which one should I use?

A.

Google Patents is a good place to begin. It covers full text patents from major patent offices worldwide and is particularly helpful for a quick identification of patent classification codes. However, it might not give you analytical solutions.

The following resource suggestions include two parts: patent databases our library subscribe, and some commonly used patent authorities' databases that are open.to the public.

Databases that requires HBS or HUKey login:

  • PatentSight: a patent database/analytics solution that allows patent quality analysis based on the Patent Assets Index Methodology. Such an analysis helps tech driven companies gain valuable insights into the strength and relative value of patents and patent portfolios. It informs decision makers and patent experts with advanced analytics in the fields of benchmarking, R&D strategy, Finding trends, M&A, licensing, and portfolio optimization. Benefit from great efficiency, profitability and fun to use. See Patent Analytics with Patentsight: 101 for quick instructions. 

Other databases with subject/disciplinary focused patent data:

  • Cortellis: pharmaceutical focused (HBS MBA students only. Access is available to HBS AND HU students, staff and faculty onsite at Baker Library (users must be logged in by Baker staff).
  • Pitchbook: patent data related to Pitchbook covered companies (HUKey and individual account set up required)
  • SciFinder:  chemistry and chemical engineering. (HUKey required)
  • Web of Science: provides patents that are associated with articles covered in Web of Science via cited reference search. (see a quick instruction) (HUKey required)
