Every year on March 17th, St. Patrick’s Day is celebrated worldwide in honor of Ireland’s patron saint. But did you know there are actual patents on inventions specifically designed to enhance our festive celebrations? When people think of St. Patrick’s Day, green beer often comes to mind first—especially for those with Irish heritage, like my wife, making me somewhat of an expert on the topic! Although adding green food coloring to beer is straightforward, patent US7878370B2 streamlines the process by enabling bartenders to color beer green as it’s poured. Talk about efficiency! In fact, there are several patents aimed at making the green beer experience quicker and easier.

Continuing with the beer theme, another iconic beverage closely tied to St. Patrick’s Day is Guinness® (Trademark Reg. No. 321014). Thanks to their innovative gas-containing insert (US6896920B1), you can now enjoy the same smooth, creamy pour at home that was once only available at your local pub.

Another beloved St. Patrick’s Day tradition is dressing in green clothing or wearing items decorated with shamrocks. If you’re looking to really stand out, patent US7393113 describes an illuminated necklace featuring ornamental lights shaped like shamrocks. For the record—that’s definitely NOT my wife.


If you are interested in looking cool, then USD335678S might just be for you.
You can increase the cool factor with your friends by bringing along your shamrock-shaped bottle opener (USD505846S).
If being silly is your thing, then might I suggest you wear the pot-of-gold novelty headwear depicted in USD672532.
Lastly, if you just aren’t into it and want to celebrate St. Patrick’s Day with the least amount of effort, then the shamrock decoration described in USD460716S is for you. Double-sided tape and you are good to go.
Happy St. Patrick’s Day everyone!
