I forgot to mention: without patents, every product becomes a commodity [false] that anyone can produce [false], so competition drives out all profits [false] EXCEPT those of the innovators who have invested in R&D and are thus offering something new that others haven't started producing yet!
Competition does not "drive out" profits. Margins are likely reduced by competition but they don't go to zero (or does "drives out all profits" mean something else?). Remember that people invest due to an anticipated or projected rate of return. If the profits are zero, there is no return and you would be better holding cash or making safer investments with a lower anticipated return.
Profits are more likely to be negative - very negative - than zero. Nobody aims for zero so the likilihood of hitting it is slim. Negative profits situation occur often because the demand or cost of a product was miscalculated. Things can be sold for a 5% loss because the alternative is a 50% loss. But I see little reason for profits to trend to zero excepting a stable market with little entry cost. Is your understanding different?
Zero-profit conditions can occur but they also require
zero or near-zero entry costs. If the widget factory costs $1 million, the output will either have a predicted profit or it will not be made (these predictions would account for the loss of patents).
Not all things become commodities due to a loss of patents. E.g., anybody can cook a steak but that does not make it a commodity. Beef of a given grade may be a commodity, but the finished product is not. Restaurants trade not just on their legal right to cook without fear of patents, but on the ability they have demonstrated to the market. If you need heart medication, are you going to swallow the lowest cost pill or will you pay a premium for a proven product?
I agree with your conclusion, nonetheless:
So no patents means an INCREASED economic incentive to innovate, not a reduced one. The truth is the exact, diametric opposite of your claims.
Ending patents will
a) increase competition
b) increase innovation and reward implementing those innovations with marketable products
c) make many lawyers cry
d) cause big players to worry about the little players (instead of just bribing Congress)
Not having a crystal ball, I can't say what profits will do. Apple makes huge profits not so much by unique things they can do but by brand loyalty, being a fashion statement, and the trust they have earned among their customers (not me). I suspect patents hurt their competition more than it helps Apple, but I could be wrong. Their profits could remain largely unaffected.
