Hepatitis C Virus patent assignments: patents with HCV in the patent claim

Posted By James Love On In Uncategorized | Comments Disabled

To get a quick look at who is holding patents on the Hepatitis C Virus, I did some searches of the USPTO database. In each search, I looked for the term HCV in the field for patent claims (ACLM). Note this is fairly arbitrary, and I get different (and higher) numbers if I include HCV in the Abstract. In any case:

There were 1164 patents that have the term HCV in the patent claim.

Of the 1164 patents with HCV in the patent claim, 75 were assigned to non-federal government owners, but disclosed federal funding and government rights in the patents, and 11 are assigned to the US federal government. Together the inventions declaring federal funding are 7 percent of the total.

There are 96 patents have the term HCV in the claims, and are assigned to an entity with the term University or College in the name. Of these 96 patents, 56 disclose federal funding and federal rights in the patents.

Country of Assignee

I also looked at the country of the Assignee

The USPTO as a field in the patent database for the country of assignment. Unfortunately, the USPTO only began to include a code for the US in 2006. For the years 2006 to the present, there were 764 patents with the term HCV in the claims. Of these, 501 patents (65.6 percent) were assigned to a US owner, and 263 (34.4 percent) were assigned to a non-US owner.

For non-US entities, the country of assignment searches work for all years, showing the assignment when the patent was granted (as opposed to any current assignments that may exist). For the all of the patents with HCV in the patent claim, from 1992 to the present, the country of assignment at the grant of the patent is as follows, for the following 15 countries.

Company of Assignment

For the company receiving an assignment of a patent with the term hcv in the claim, these are results for the following companies :
(Note, this is not an exhaustive list)

Other

These selected universities and governments are recipients of assignments of patents that have the term HCV in the patent claims.
(Note, this is not an exhaustive list)

Note, companies acquire patent licenses and patents from third parties, and may assign patents to companies with different names, including subsidiaries.

Finally, these are the numbers of patent grants, by year.
