RWS has a team dedicated to obtaining legal status information, file wrappers, copies of technical papers, articles and patents, to ensure you have all the records you need.

File Wrappers

Not all patent offices provide online file wrappers, and even if they do, the online content may not be fully updated. We provide copies of all official documentation and correspondence which relate to any granted patent or published patent application.


Our offices are located close to the British Library in London, home to the largest collection of patent and nonpatent technical literature in the world.
