Design around

U.S. patent law
To design around means to invent an alternative to a patented invention that does not infringe the patent’s claims. The phrase can also refer to the invention itself.

Design arounds are considered to be one of the benefits of patent law. By providing monopoly rights to inventors in exchange for disclosing how to make and use their inventions, others are given both the information and incentive to invent competitive alternatives that design around the original patent.
