Patent Only Worldwide (PatBase records) 2,250

Requirements

Publication number of patent to be invalidated, with an indication of claims / features of interest, plus any prior art (if available).

Strategy

Patent: The strategy will usually be a combination of

  • Classifications (IPC, ECLA, DEKLA, USPC, CPC and / or Japanese FI / F-Terms) either via specific headings or using classes-in-combination as appropriate.
  • Keywords, “pure”’ and / or in combination with classification headings.
  • Citation searching, forward and backward.

The methods used are ultimately determined by the subject matter of the search and the constraints of the budget.

Non-patent: Primarily by keyword, although database specific classification schemes may be utilised.

Supplementary applicant / inventor / author searches may also form part of both strategies.

Coverage

Patents in full text and / or abstract format are accessed through PatBase, the database developed by RWS and Minesoft covering more than 45 million patents from over 100 issuing authorities: US, WO, EP, GB, DE, FR, CN, JP and many more.

Technology-specific abstract databases will be the resource for non-patent literature. Where possible, full articles will be inspected for any abstracts of potential interest.
