If I want to make an elizabethan collar just using the standard

This answer was rated:

If I want to make an elizabethan collar just using the standard plastic cone, will I run into patent issues? If so, how much do I need to change the collar so that it doesn't violate a patent?

Will it be enough to use a different kind of plastic or different mechanism for connecting the cone together (e.g. velcro)?

RobertMcEwenEsq :

Thank you for using JustAnswer. I am researching your issue and will respond shortly.

RobertMcEwenEsq :

There were plastic Elizabethan collars in 1978 (at least) (see Patent 4,200,057) and as such, the 20 year period has long expired.

RobertMcEwenEsq :

That means that you should not run into any patent issues if you have a standard cone collar connected with Velcro. I found a patent with Velcro connecting it filed in 1991, and even that's past 20 years.

RobertMcEwenEsq :

So in short, any patent protection for that type of collar has run.
