Heart-Shaped Chocolate Box

Chocolates and other assortments of candies have been associated with this holiday for many years. Chocolates, in fact, are so popular that a whopping 58 million pounds are purchased during the week leading up to Valentine’s Day. This heart-shaped chocolate box patent was granted to Shanghai Longlian Packing Material Co., Ltd. in 2017 and is among the 35 million heart-shaped boxes of chocolates that are sold the week of Valentine’s Day.

Social matching

Eharmony, an online dating site, claims that every 14 minutes someone falls in love on their website. With those kinds of statistics, it’s to no surprise that they have patented their methods. Eharmony’s patent for Social Matching was granted to them in 2019 which takes into consideration the subscriber’s friend’s input on potential matches based on a matching engine performed by an internal processor. Does it work? Well, if you are single and ready to mingle this Valentine’s Day find out!

This jewelry box was patented just last year for its unique blue fluorescence light that illuminates the jewelry when the box is opened – sure to give your gift that wow factor.
