Ok let me simplify my situation a little bit..I am using a 24LC32 serial eeprom from microchip. Now, isnt that an I2C 2wire bus device? If so, the code I am using to read and write to the eeprom I of course have written myself, I am using a 16F84, so i would not have to obtain a license to distribute my product correct? Now if the 24LC32 is not an I2C device they coulda fooled me. In that case phillips dont exist in this ; ) and how does one get away with that? By calling it a serial eeprom instead of an I2C eeprom or some kind of legal trickery. Like Vanella Ice claiming he had 1 more beat added in his song, so technically he did not steal the Queen song..im sure.
