i would be concerned about any algorithmic changes regarding irrelevant run-of-site links or anchor text. this has been discussed many times here over the years. if you are interested in reading thoughts previously expressed:
I'm reminded of a forum software company having PR10 on their home page, they had a link on every page of every forum in use. That was dropped to PR5/6 right around the time Google made the first announcements about sitewide links and footer links. I don't know for sure if that is the cause of the PR drop but the timing was right.
My point is that sitewide footer links likely don't help and may actually hurt your efforts. I'd just mention the company name but leave out the link at this point, or perhaps make any software (or web design) have a link on only a specific page, such as at the bottom of an *about* template page only.
