The problem is, in the US at least, that companies have entire rooms full of
patent lawyers whose job it is to file patent claims for every idea that
flashes between the synapses of an employee on company time. Cobble
together a high-falutin' description, toss in a few CADCAM diagrams, and
voila! The USPTO is easily impressed. Problem is large majority of those
patents are never developed beyond the initial concept.

Then they have other rooms of more patent lawyers whose job it is to scour
the world for anything that vaguely resembles a patent already held by the
company.

The result is there are so many spurious patents today that it becomes very
difficult to develop non-infringing new technologies.
