Acme Co Developed and Made a No-Drip Faucet

Acme Co. developed and made a no-drip faucet. Before it actually marketed the product, however, Acme investigated and discovered that its faucet infringed a patent belonging to Bigelow Co. Because Acme acted in error, without intending to infringe, and because it discovered that error prior to marketing the faucet, Acme is not liable for infringement.
