Patentability Searching & Opposition Studies


J&B Partners was set up in 2010 by Steven Johnson and Vedran Biondic to provide a high quality client-focussed service. With expertise in chemistry, life sciences and mechanical and electrical engineering technologies, our searchers have worked for large independent search companies for a number of well-known clients on a national and international scale.


We have a significant amount of experience in patentability searching, opposition/validity studies and infringement and freedom to operate searching, utilising the most up to date patent databases and non-patent literature resources.


We can link patent and scientific literature with commercial data to complete landscape and patent mapping studies to help clients answer business questions and understand different technology areas. Members of the team are also well practised in conducting design and trademark searches through a number of different territories around the world.
