I always try to enumerate anything and everything that I can of existing projects and inventions. Enumerate every repository on Github. Enumerate a title (can be very ambiguous) of every idea or concept that you are working on. Enumerate any consulting work you've done in the past and a "consulting" item.
At the very least, the advantage of this is that it drastically increases the legal cost in researching to see that what you wrote was not enumerated or covered in any way by the enumeration.
