The services of the patent attorney comprise:

Search on the state of the art
(Patents and utility models)

These are, on one hand, specialist searches in order to especially search a technological specialist field according to patent classes and, on the other hand, name searches through which for example the protection rights of a specific firm are ascertained

Registered design search

Trademark search

Observe that you:

search properly
search continually
search comprehensively
search on time

You can save on costs if you search yourself, but then you should get advice from your patent attorney prior to laying down the search strategy.

It is equally important to bring in the patent attorney when analysing the search results.
