Recently, the topic of “room temperature superconductivity” has been trending. First, a researcher from Lawrence Berkeley National Laboratory (LBNL) in the United States published a paper providing theoretical support for the superconductivity of the Korean research team’s material LK-99. Later, the LK-99 research team stated that the paper had defects and was published by team members without authorization. They have now requested its removal, causing a public outcry. On the other side of the Earth, the American company Taj Quantum claims to have discovered another room temperature superconductor material and has obtained a patent. The capital market was moved by the news, and A-shares of superconducting concept stocks collectively rose sharply in the afternoon. The US stock market, American Superconductor (AMSC), continued its upward trend before trading, rising over 100% at one point.
ScienBiziP found through relevant information that Taj Quantum, a company based in the United States, has indeed obtained the relevant patent (the original text indicates patent number 17249094). After search confirmation, the patent application number is 17/249094, patent number is US11710584, and the patent title page is shown in the following figure:

From this publicly available patent, we can obtain several pieces of information:

1. This patent application was submitted in advance through a provisional application, with the provisional application date being February 21, 2020, and the formal application was submitted within its 12-month priority period, which is February 19, 2021 (2 days before the legal deadline). It can be imagined that research and development should start very early, patent applications should be timely and have good strategic planning, which is worth learning from.

When new products and technologies emerge, applicants can take advantage of the advantages of temporary patent applications in the United States (see attached figure for details) to obtain an early application date and gain a good market advantage.

2. The entire manual provides a brief explanation of the preferred embodiment, consisting of only two natural paragraphs, and the specific implementation method is not yet complete. The original text and accompanying drawings are excerpted in the table below. Simply put, multiple layers of porous material layers 24, 26 and an external protective layer 28 are formed on a non-conductive substrate 22 to ultimately form a wire 20 structure (not limited to wire shape), and then special arrangements are made for the wire 20 (see Figure 3) to form superconductivity. It is recommended that future R&D personnel and related field enterprises carry out a supplementary layout of arrangement structure.

In summary, when applying for a patent, it is not only necessary to pay attention to patent writing skills and clearly define the scope of patent protection, but also to grasp relevant policies and regulations, use application channels and strategies reasonably, in order to protect the innovative achievements of enterprises one step ahead and help them develop in the long run.
