Purpose (plain language): The patent describes applying polymer materials to roofing materials by a printing-type methodology to form nail tabs or reinforcing strips. Instead of laminating or otherwise attaching a separate reinforcing piece, a polymer material is deposited onto a substrate in a patterned manner, e.g., as a tab or strip. Source classification supports this: B41M3/00 (printing processes to produce particular kinds of printed work) and B41M7/0081 (after-treatment of prints using electromagnetic radiation such as UV), alongside coating-by-contact apparatus classes B05C1/00, B05C1/08.
Scope indicators from the excerpt: The listed prior-art keywords are roofing, tab, tab material, tabs, building cover. Term-frequency data indicate the description discusses substrate, liquid, adhesive, asphalt, saturated elastomer, thermoplastic, thermosoftening plastic, fibreglass, composite material, elastomer, mixture, polyester, UV light curing adhesive, transfer printing, gravure printing, and offset printing. Claim/abstract concepts include method, manufacturing process, lamination, deposition, adhesive and adhesive effect. The excerpt does not reproduce claim text, so exact claim boundaries cannot be stated.
What the excerpt does not establish: It provides no claim language, no written description, no drawings, no examples or process parameters, no priority-chain detail beyond the listed dates, and no evidence on validity, enforceability, or claim interpretation. The listed assignee and legal status are explicitly described in the source as assumptions or unverified.

No PTAB proceedings on file. This patent has not been challenged via IPR, PGR, or CBM. The absence is itself a signal — well-asserted patents eventually attract IPRs. The LLM analysis below may surface filings the ODP feed hasn’t indexed yet.
PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
