Ранее я делал серию постов про битовые операторы. Вот вам ещё один наглядный пример как это используется в Python в модуле re. Чтобы указать флаг для компилятора нам надо указать его после передаваемой строки. Например, добавляем флаг для игнорирования переноса строки. pattern = re.compile(r"(\w+)+") words = pattern.search(text, re.DOTALL) А как указать несколько флагов? Ведь явно будут ситуации когда нам потребуется больше одного. Кто читал посты по битовые операторы уже понял как. pattern.search(text, re.DOTALL | re.VERBOSE) А теперь смотрим исходники, что находится в этих атрибутах? Не удивительно, степени двойки. Почему? Потому что каждое следующее значение это сдвиг единицы влево. >>> for n in [1, 2, 4, 8, 16, 32, 64, 128, 256]: >>> print(bin(n)) 0b1 0b10 0b100 0b1000 0b10000 0b100000 0b1000000 0b10000000 0b100000000 Чтобы было понятней, давайте напишем тоже самое но иначе, добавим ведущие нули: 000000001 000000010 000000100 000001000 000010000 000100000 001000000 010000000 100000000 Не понятно что тут происходит? Читай три поста про битовые операторы начиная с этого ➡️https://t.me/pythonotes/45 В общем, это пример применения побитовых операций в самом Python. Теперь вы знаете Python еще немного лучше) #tricks#regex#libs

🇺🇸USPTO Withdraws AI Strategy Amid Policy Shift The U.S. Patent and Trademark Office (USPTO) has officially withdrawn its AI strategy document, published in January 2025. Acting Director Coke Morgan Stewart cited that the strategy was influenced by Biden-era executive orders, which have since been rescinded by the Trump administration. The new AI policy direction focuses on deregulation and strengthening U.S. global AI dominance—though specific implementation details remain unclear. Key legal questions now come to the forefront: Will the U.S. redefine AI inventorship, potentially allowing corporations to be named as inventors? And how aggressively will the USPTO integrate AI into the patent examination process? These issues could reshape both intellectual property law and AI governance in the years ahead. #AI#PatentLaw#USPTO#AIGovernance#AIRegulation

🇺🇸USPTO Reframes AI-Assisted Invention: Human Inventorship Remains the Rule The U.S. Patent and Trademark Office has issued new guidance confirming that AI may support invention but it cannot share or replace inventorship. The USPTO rescinded last year’s AI-specific guidelines and returned to a uniform standard: the same inventorship test applies to all inventions, regardless of whether AI was used in the process. Generative AI is now formally treated as “laboratory equipment” or any other research tool that assists a human creator, not as a co-inventor. Notably, the Office rejected the prior administration’s “joint inventorship”-based framework for determining patentability of AI-assisted inventions. Instead, examiners must ask a single question: did a natural person conceive the invention under traditional doctrine? Courts have already held that AI systems cannot receive patents, but they have not yet ruled on the boundaries of human inventorship when AI is deeply embedded in R&D. This updated guidance will likely shape that future litigation. #AIandLaw#IntellectualProperty#PatentLaw#AIRegulation#USPTO#AIGovernance

OpenAI's Trademark Application for 'GPT' Denied Greetings everybody! The US Patent and Trademark Office (PTO) has rejected OpenAI's bid to trademark the term 'GPT' (generative pre-trained transformer), citing its generic nature. According to the PTO, granting the trademark could impede competitors from accurately describing their products as GPT. OpenAI argued that 'GPT' isn't merely descriptive and doesn't immediately convey its meaning to consumers. However, the PTO emphasized that those familiar with the technology understand 'GPT' as a general type of software, not exclusive to OpenAI products. The decision marks a setback for OpenAI, whose association with 'GPT' grew significantly with the popularity of ChatGPT and its subsequent AI models. Despite previous denials, OpenAI may appeal to the Trademark Trial and Appeal Board for another chance to secure the trademark. #OpenAI#GPT#Trademark#USPTO#AI
