Did Audi apply for a patent for the juxtaposition of daytime running lights and headlights?

As far as the models can be seen at present, the design of Audi's daytime running lights and headlights is not necessarily a patent. Regal designed by GM Europe Center is a headlight wrapped with daytime running lights. In my impression, Audi was not the first to use daytime running lights, he was only the first to use LED daytime running lights. Northern Europe is foggy, so local legislation requires all cars to be equipped with automatic steering daytime running lights. At that time, it was a halogen bulb, and many models were installed in headlights. Audi added LED daytime running lights for production cars for the first time in R8, which is amazing. Thereafter, A3, A4, A5, A6, A7, A8, TTS, TT RS. Q5, Q7 ... Each new model is equipped with the iconic eyebrow-shaped LED running lights. Many other models, such as Aston Martin and Buick Regal, are the same as Audi. Aston Martin DB9 headlight group has a pair of LED daytime running lights, and the outer corner of the headlights of the new Regal is a beautiful daytime running light. The headlights of Porsche cayman are the same, except that the daytime running lights of BMW's new 5 series are not LEDs, but two rings, called angel eyes, hehe. It is also unique. I really don't know if Audi's design is patented, but I told you everything I know, hehe, I hope it will help you. Thank you. I hope you can adopt it!
