Details of the article, apparatus or process, together with an indication of what aspects are considered to be of greatest significance.


Designed to locate the most pertinent cases liable to cause concern, the strategy will usually be a combination of:

  • Classifications (CPC, IPC, ECLA, DEKLA, USPC 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.

Supplementary applicant / inventor / author searches may also form part of the strategy.


Patents in full text and / or abstract format are accessed through PatBase, the database developed by RWS and Minesoft.

Whilst the focus of the search is on the claims, and cases which are potentially in-force, disclosures indicating possible right-of-use are also reported.



  • All pertinent publications located, with technical comments as to relevance or otherwise.
  • Patent family information, with representative abstract and image (where readily available).
  • Unofficial status information (from readily available sources).
  • Details of the strategy employed (periods, countries, class definitions etc.).
  • Recommendations for extension of the search (if appropriate).
