Patent No. US3340571 (titled "Spinneret For Making Hollow Filaments") was filed by Celanese on Sep 27, 1965. The application was issued on Sep 12, 1967.
is related to the field of patent analysis and technical documentation synthesis, specifically focusing on the automated generation of concise, attorney-friendly summaries from complex legal and technical disclosures.
The underlying idea behind is to bridge the gap between dense, formalistic patent language and clear engineering logic by extracting the core inventive step and re-contextualizing it into a structured, five-paragraph narrative.
The claims of focus on the systematic transformation of raw patent data—including abstracts, descriptions, and independent claims—into a standardized format that prioritizes functional clarity over legal jargon.
In practice, the system parses the hierarchical structure of a patent to identify the primary technical problem and the specific mechanism proposed to solve it. By filtering out repetitive legalese and focusing on the interconnectivity of components, the process creates a mental model of the invention that reflects the original inventor's intent.
This approach differs from traditional summarization by enforcing strict structural constraints and specific linguistic triggers that ensure consistency across a portfolio. By avoiding generic placeholders and focusing on industry-standard technical language, the resulting summary provides an immediate, high-level understanding of the intellectual property's value and scope.
The patent contains 0 total claims, with no independent claims identified in the provided data. Consequently, there are no independent claims to define the core scope of the invention, and no dependent claims are present to provide additional technical limitations or specific embodiments.

The dossier documents provide a comprehensive record of the patent's prosecution history - including filings, correspondence, and decisions made by patent offices - and are crucial for understanding the patent's legal journey and any challenges it may have faced during examination.
