Yes, you can lose patent rights by inaction, but it's less about a direct "loss" for not suing and more about abandonment or failing to pay fees, though not defending against infringers can weaken your position and lead to potential claims of abandonment or loss of value, especially for trademarks, while patents often expire naturally or are challenged on grounds like inequitable conduct. While not actively suing doesn't automatically invalidate a patent, letting infringement run rampant can be seen as abandoning the invention, and you lose the ability to generate income from it, making it less valuable.
