I've read so much in this past year about patent applications--the ups and downs, insides and outs of doing it yourself vs. hiring a patent attorney. My provisional patent (which I secured myself) is coming to an end and I would very much like to finally have the official patent for my product. My product is no Dyson vacuum--it's a small entity, a special hair accessory. I would like to hear from anyone who has successfully filed an application themselves, received their patent and how they went about doing it. If you receive a patent, why would it be any less valid if you applied for it yourself vs. filing your application via an attorney? Thanx in advance for all of your ideas!
