FreePatentsOnline has partnered with Technology Transfer Tactics, a website for university tech transfer professionals, to provide a resource for searching university-owned patents.
Data for about 150 universities (mostly American) is available. Clicking on a name of a university will retrieve a list of US patents and published applications assigned to that university.
The number retrieved may be different from what you retrieve in a manual search. For example, the link for Johns Hopkins University retrieved 1,766 documents, but I was able to retrieve 1,950 documents in FPO using the search query an/"johns hopkins". The same search in the USPTO databases retrieved 1,852 documents. It's not clear why this is so, but it may be because the data in the university patent search is not in sync with the live FPO database.
