Since 1995 I've created about 80 websites. Some stay online for years. Some fail to achieve their goals or simply become unnecessary, and are deleted from cyberspace. At any particular time, about 30 of my sites are online.
Over the years, about 100 competitors (that I know of) have copied my designs, words and photographs. One thief, Hindustan Telecom, was so stupid that it even copied my list of customers. The Indian idiots are still displaying words I wrote and graphics I devised more than 10 years ago!
Usually the thieves will remove the purloined intellectual property after I send them an email, without involving the law or lawyers. My standard message includes this line: "It takes big balls to steal unique intellectual property. It takes a small brain to display the stolen property where everyone can see it." The owner of the company or operator of the website usually apologises and blames an employee or other third party.
Last night I discovered a new kind of theft.
A few years ago I designed a Batphone for sale by my company. They're made for us and we are the only source.
