My comments:
An American idiom, this phrase usually appears in the negative, e.g. “you don’t have to reinvent the wheel.”
Meaning?
You may need to make small changes and improvements, but there is no need to uproot and overhaul the whole existing system.
The wheel is what makes a vehicle move, and this ring-shaped thing has been around for thousands of years. People may use different materials these days to make the wheel tougher and smoother to run, but last time I checked, it is still round shaped.
Hence, by saying one doesn’t have to reinvent the wheel, they mean to say that minor adaptations or changes are needed instead of anything radical.
In our example, “you can integrate IP protection into your existing improvement program without” developing a brand new system from scratch.
