Yes. Think of it this way at $2000 USD an hour ( cheap for a top law firm with the relevant expertise ) $600K USD is only 300 hours of representation. Figure roughly 10 hours a week and suddenly 6 months of negotiations looks damn near impossible for anyone less than a multinational.

Patents are one of the few areas of the law where it's cheaper to attack than defend. And at present they are the greatest threat to the most dynamic sectors of an otherwise sclerotic economy.

Any politician that is not actively pushing to reform the patent issuance and defense process is blasting the seed corn with a blowtorch. Burning the future.
