at least, you should be able to use the patent in your authorship part,
which is a publication too.
Next, you can try to search if your patent being cited anywhere, which will
be a nice evidence of its impact. (counted as citation in my case and
mentioned in contribution too)
Thirdly, if your patent is being used in any product of the company, then
you can claim your contribution via the market coverage/dominance of the
product and the sales revenue of the product.
