Legal analysis: This question depends on what patents others apply for, because there are three kinds of patents. First, invention patents protect certain ideas, or methods, or processes, or formulas, such as chemical and pharmaceutical industries. The second kind of utility model patent protects the improvement of the tangible structure of the product, and the third kind is the design patent, which protects the combination of the external structure of the product with color and pattern. If you mean that others have applied for the second kind of utility model patents, you should apply for one or more utility model patents as a preventive measure according to the differences of your internal electronic components. If someone else applies for the design patent of the product at the same time, your product can't be produced, or you can continue to produce by changing the appearance of the product.
