I haven't seen that sort of design used to charge a computer mouse before, but I have seen the "coil + natural magnet" design used to provide power for other sorts of devices that were being moved or operated by a human (exercise equipment, RFID tags, flashlights, etc). Wireless mouse charging (by other means) is not new, so it's unlikely that the combination of the two would be considered novel.
We don't plan to pursue this in a commercial capacity. Basically,
we're just looking to add it to our resumes.
If you're just looking for a resume booster, don't waste your time with a patent. Patents aren't cheap, and you won't be able to put it on your resume for years since it takes a while for an application to make its way through the system. The work that you did in designing and implementing the charging system is the real resume-worthy material, anyway. The only difference between saying that you "designed" such a system and "designed and patented" it is that you demonstrate that you're capable of hiring a lawyer to do some paperwork. If you were planning on selling the technology to another company, then it would be a different story (being able to point to a product currently on the market and say "I invented that" is a big resume booster).
