I am developing some electronics technology (digital hardware and firmware)that I will be licensing to other companies for integration into their consumer electronics products. Of course, I will have some type of licensing agreement. However, I still wonder if it is worth copyrighting my schematics and firmware. A patent is not justified, due to cost, time and the fact that the claims would be quite narrow. The concern is, how easy is it for someone to slightly modify my schematic or firmware to circumvent copyright violation. My firmware will be protected somewhat, since it resides internally to a PIC microcontroller, with the code protect feature enabled. I will be shipping pre-programmed PICs to the licensee. But I would still like to pursue some type of copyright, if it offers another layer of protection. In addition, I developed a network interface to the technology I have developed. Where one can use a PC or any device with a RS-232 port (if they write the appropriate software) to control and monitor the additional functions that my technology adds to a consumer product. ASCII commands are sent to the unit for control purposes. ASCII commands are sent FROM the unit for monitoring purposes via a remote GUI. This protocol will be public domain. The bottom line, is I want to prevent another company from using the same network interface protocol in their products without my written consent. Since if they do, THEIR products will be compatable with all the existing GUIs, I and consumers develop, to interface with my technology in my licensee's products. I want to legally prevent this. Can a copyright help with this also? Thanks __________________________________________________ Do You Yahoo!? Make international calls for as low as $.04/minute with Yahoo!
