It makes perfect sense. Unfortunately patenting an invention has its price. Even if you were to prepare an application yourself, there are still governmental fees.
Questions to ask yourself:
A) Do you truly have a lot of inventions or do you simply have a lot of ideas? In other words, have you been able to make, use, and test your inventions?
For an Edisonian example, while most of the attention related to the discovery of the light bulb was on the discovery of the right kind of filament that would work, Edison had to invent a total of seven system elements that were critical to the practical application of electric lights as an alternative to the gas lights These development were:
1) the parallel circuit,
2) a durable light bulb,
3) an improved dynamo,
4) the underground conductor network,
5) the devices for maintaining constant voltage,
6) safety fuses and insulating materials, and
7) light sockets with on-off switches.
You don't always know what is all involved in the idea until the invention is complete.
B) Is there a real market for your inventions? Edison made millions, but came up with million dollar inventions.
