The item was not designed to be disposable. I used that term because the cost of repair would exceed the purchase cost.
A patent requires the details of an invention be published publicly so a patented device is not proprietary. To defend a patent against infringement is very time consuming and expensive. I hold a patent which was infringed and in the 1970s the estimated cost of defense was $100,000 which was out of budget for my employer. This was an interesting case since the patent was for a medical device and the medical research foundation where I was employed obtained the patent for the purpose of encouraging a manufacturer to produce and market the device under license so it could be widely used in patient care. Negotiations were going well until a foundation lawyer interfered in the negotiations without our knowledge and screwed it up. It was infringed by another manufacturer and we didn’t pursue it since the device was being used which was our original intent and the amount of royalty would not have been substantial.
Thing don’t always work out as it seems they should.
