Let's suppose you're a large semiconductor company who is currently making a large amount of money selling chips to a couple of major customers. You've decided that your business is too big and you have no desire to get new customers, now or in the future. In fact, you don't even want these companies to use your products in new designs. What are some ways you can get rid of these pesky engineers trying to throw money at you?
- Make your parts hard to find. Ask major distributors like Digi-Key and AVnet to discontinue stocking them.
- If someone does manage to find an authorized sales partner, pester them with questions even if they're just looking for a budgetary price quote for a feasibility study. Ask for a project name, description, business plan, names of the team members, color of the soldermask, logo, and anything else you can think of. If it looks like an initial proof of concept that the customer isn't yet confident will become a high-volume product, or a one-off test fixture/lab tool, badger them by asking about annual sales volume and volume ramp-up dates until they lose interest and buy from a competitor.
- Just in case anyone actually succeeds in buying your part, make it useless to them. Keep the datasheet locked up in a steel vault in your corporate headquarters. Promise would-be customers that you'll let them see it if they sign away their firstborn son and sacrifice a golden lamb on an altar made of FPGAs, but hide the actual NDA contract behind so many redirect pages and broken links that nobody can actually sign it, much less see the actual datasheet. Bonus points if your chip is something commodity like a gigabit Ethernet PHY that has nothing even remotely sensitive in the datasheet.
