Patent search: Product-associated patents

How can I find patents associated to a particular (branded) product?


It is always a challenge to conduct a patent search by product (or "brand name") because:

  • Almost all the patented products in the market are known by a brand name or trademark, e.g. Segway® (Personal Mobility Vehicles and Methods)
  • Product names rarely appear in patent documents 
  • Product name may change 
  • A patented technology may be used in many different products with different names

Below are some tips for finding patents by product:

  • Search the name of the product's inventor in patent databases, if known.
  • Search the product's name in a trademark database to identify the owner. Then search the owner's name as Assignee in a patent database. This works if the trademark owner is the original owner of the patent.
  • Check product label, manuals, or packaging. Companies usually physically or virtually mark their product with patent numbers in order to protect their patent right. (e.g. Pat. 12,345,678, Pat., or Pat.pending.) 
  • Check company website. Some companies may lists patents associated with their products on their websites. 
  • For pharmaceutical products associated patents, use Cortellis. Access is available to HBS AND HU students, staff and faculty onsite at Baker Library (users must be logged in by Baker staff).
