There is a danger of browsing software patents. In the US and other countries which permit them, if you're sued and it can be shown that you browsed the patent, they can get you for willful infringement, which is worse than infringement, and attach 3x the penalty which would otherwise be assigned.
Some patent suites that offer you (unasked for) results from your Google searches record the IP address and page view of everyone who visits them. They then offer this information to IP holders for a fee. The idea is IP holders will pay to see if the entity they are suing or anyone coming from their company's domain viewed the patent.
Don't click on patent site links. It would be better to report it as spam unless you were actively looking for a patent.
