I'll take a crack at that one.
We have basically two types of applicants. We have those who are represented by a professional IP agent—who is typically a lawyer with an engineering background, if it's in the patent world—and we have unrepresented applicants.
If you do hire a lawyer, as I mentioned before, the costs will vary, but $20,000 to $25,000 is likely in the range of what you're going to pay. If you come in unrepresented, you don't get that counsel. The IP world is very complex from a legal perspective, and some of our more troublesome application processes have been with people who have been unrepresented, because they don't understand the law.
We actually do encourage our applicants to hire a good IP agent to represent them. Basically, if your idea is worth protecting, it's worth protecting right. Even if you're unrepresented and you do get a patent, does the patent represent the scope that it should? Are you still well protected? Because you didn't have benefit from legal counsel, you may not have the result you were anticipating. So we do encourage that our folks seek counsel.
