Here I think BennyF may have a point at least correct 25 or so years ago.You've just described how to create a readable schematic, which is sort of a prerequisite for any electronics work whatsoever.
Again, I think you may not understand how the patent system works if you're worried about that. Google "priority right."
I am very frugal guy - do almost every thing for myself, by myself, but I did talk to APL's patent group, which files about a patent each week, before doing my own. I would never have made so many general claims, each one a little more specific than the prior ones, so I hired (for after hours private work) one of APL's patent experts to write my claims.
I had a high quality drafting courses at Cornell -two three hour labs each week for one year. Yet when I looked into it, and listened to what the APL patent office told me and did*, I decided to hire a patent specalized draftsman to make my India ink drawings.
I don't know if the requirement are still so detailed or not, but back then you had to know which pen tip to use to get the lines exactly the width required with the slope them at just the specified angles to convey specific information, etc. Circuit drawing may be easier.

* they too hired professional patent draftsmen.
