If you have a patent, and I use the patent to sell a product, why shouldn&#x27;t you as patent holder be able to get an injunction to prevent me from selling the product?<p>Also, what does &#x27;reasonable financial compensation&#x27; mean? Consider newly patented drugs. The R&amp;D cost is enormous, even without covering the cost of the attempts that failed to get to market. And there can be multiple patents, including the method of action and the method of synthesis.<p>If you have 5 patents for drug X and I infringe on 3 to make a competing drug X&#x27;, do I pay less than if I infringe on all 5 patents?<p>(Edit after several people commented: I believe that amelius meant to include mandatory RAND-like licensing for first sale. My response should be read in that vein.)
