LASER EPILATION AND USE PATENTS From: jayroth@azstarnet.com (James G. Rothschild) I've used the ND-Yag LASER for tattoos and lentigines. I read in Dermatology Times about using the LASER with a carbon emulsion to remove unwanted facial hair. The parameters were 7mm. spot size and power of 2 joules/cm2. Does anyone have the complete protocol and advice regarding obtaining the particular carbon emulsion? Would appreciate hearing about anyone's experience and also any anticipated side-effects such as hyperpigmentation etc. =========== From: MerrillC@aol.com I have contacted the company representative named in that article. Apparently that company has a use patent, which means it can limit the use of the procedure any way it wants. What they have in mind is to allow the performance of the procedure at their own licenced centers only. The plan is to open one "in every major city", but the first one is to open in La Jolla this year and nothing else before next year. The rep says that this is to "protect the shareholders' interests." Too bad that they don't realize they could make a lot more for the shareholders by making it widely available to physicians who do laser work. If you hear any more about it, especially anything positive, I would like to hear about it, since I have several patients that have heard about it too and would love to have it done. However, they don't want to travel so far. I also spoke with physician named in the article--apparently it might not be permanent, but might require at least two treatments. The YAG laser is used at power setting at half to one-third (or maybe less) of that used to treat tattoos, so side effects should be minimal, if any. ==================== From: ecgomez@ucdavis.edu There are basically three types of patents: Composition of matter patents Process Paternts Use Patents The first is like finding a new chemical and covers all uses of that chemical. The second is like development of an industrial process, such as the method for synthesizing a compound, such as cortisone. The Use patent is really a variation on the Process Patent, in that it describes a method (process) of using a compound or treatment. Examples of this are "Buff Puff", Retin-A for acne, etc. There has been some discussion of whether patenting surgical procedures, such as flaps, etc. is reasonable. Your comment is the first time that I have ever heard the position that the patenting of a new use for a device or cheical agent is a violation of medical ethics. Taking that position, most of industry would be guilty.
