Type of Patent Searches…
State of the art searches
How far to go and when to stop will depend very much on the nature of the query and the extent of the material found.
A limited number of hits can be analyzed thoroughly; where there is a great deal of prior art, if the search can’t be refined then it is reasonable to adopt a broader approach and bring the search to a halt.
Novelty / Patentability Searches
The scope of these searches is generally narrower than a state of the art search. You could decide to stop your search when:
- The prior art has been found for all claims of interest that demonstrates that these claims lack novelty or inventive step
- A point has been reached where the claims diverge widely from a central idea and it’s not clear which direction is preferred
Remember that it is sufficient to demonstrate a lack of novelty if you can find even a single document that describes the features of a claimed invention, assuming that this document was made available to the public before the patent in question was filed.
But if you find few or no relevant documents, you may be tempted to keep going on and on with your search. Use your experience and common sense to make up your mind – some ideas are actually new!
Freedom to Operate Search
Freedom to operate searches are generally limited by:
- The particular technology in question
- The countries in which you or your client expect to operate
- The legal status of any patent documents found, whether a patent is still in force or expired or whether a patent application can still be filed for the same invention elsewhere
Unlike novelty searches or validity searches, you should be aiming to find all potentially relevant documents. Otherwise you or your client might risk infringing a patent you didn’t even know existed, because you missed it in your search!
Similarly to novelty/patentability searches you will want to find documents that describe the features of a claimed invention. However, you will likely want to probe available documents more exhaustively to find more results that might demonstrate lack of novelty or inventiveness, in case one of your documents is rejected.
