Here are some interesting facts about technology patents in the US that can grab attention:

• Amazon patented the process of taking a photograph against a white background. The patent is so broad it covers most product photography.
• Microsoft patented the concept of auto-complete on mobile devices. So when you type a few letters and see options to complete the word, that's covered by their patent.
• Apple patented the rectangular shape of its devices with rounded corners. At one point they even tried to sue Samsung for having similarly shaped phones and tablets.
• IBM patented Ecommerce itself by patenting the one-click checkout process. So essentially they patented the concept of buying things online with a single click.
• There are patents approved for algorithms and software that many argue are overly broad and not truly novel inventions. This has been an ongoing controversy around technology patents.
