The U.S. Patent and Trademark Office ( USPTO ) has just unveiled a new patent cover design to celebrate the awarding of one billion patents this summer. Since 1790, the design of the cover of the U.S. patent certificate has changed many times, but it has changed only twice in the past 100 years. This new cover design will be used for the first time in the 1 million-patent. All subsequent utility patents, plant patents certificate covers, and design patents will use this new cover design.

According to the USPTO, "The current cover design version began more than 30 years ago and does not strongly reflect the significance of the patent certificate. The new cover design respects the history of the patent system and highlights the significant value of patents."

As shown in the chart below, the number of US patent grants has steadily increased to more than 300,000 units per year over the past decade, with foreign patents accounting for about half of the total. The last picture shows the major countries that have obtained US utility patents. The number of granted patents obtained in mainland China (excluding Hong Kong, Taiwan, and Macao) and South Korea has shown rapid growth, while the number of granted patents obtained in Japan has been declining. Germany is in a stable state, and China is expected to catch up with other countries as soon as possible in 2018.
