Summary for Patent: 10,920,211
Title:Serine protease molecules and therapies
Abstract:Cell-targeted serine protease constructs are provided. Such constructs can be used in methods for targeted cell killing such as for treatment cell of proliferative diseases (e.g., cancer). In some aspects, recombinant serine proteases, such as Granzyme B polypeptides, are provided that exhibit improved stability and cell toxicity. Methods and compositions for treating lapatinib or trastuzumab-resistant cancers are also provided.
Inventor(s):Michael G. Rosenblum, Khalid Amanali MOHAMEDALI, Lawrence H. CHEUNG
Assignee:Research Development Foundation
Application Number:US16/575,715
Patent Claims:see list of patent claims
Patent landscape, scope, and claims summary:

United States Patent 10,920,211 claim analysis and US patent landscape: What’s protected, what’s vulnerable, and where generics can design around

Executive summary: US 10,920,211 is analysable only if the complete claim set (independent and dependent claims) is provided. The prompt ends at “The claims are:” with no claim text or claim list. Under the operating constraints, no patent-claim-by-claim analysis, claim charting, or validity/strength assessment can be produced without the actual claim language.

What patents protect the subject matter of US 10,920,211

No claim text is available, so protection scope and related-family coverage cannot be determined.

What are the key independent claims in US 10,920,211 and what do they cover?

No claim language provided, so independent-claim scope, essential elements, and limiting features cannot be assessed.

How many claims in US 10,920,211 are method, composition, formulation, or use claims?

Claim classification requires the claim list or full text.

How strong are US 10,920,211 claims against obviousness and anticipation under 35 U.S.C. §§ 102 and 103?

Strength depends on (i) claim elements and (ii) the relevant prior art mapping to each element. Without claim text, no element-by-element analysis can be performed.

What claim elements are likely to be construed narrowly (means-plus-function, step-plus-function, or functional language)?

Requires the actual wording of each element that may trigger special construction.

What is the most likely invalidation path: novelty, obviousness, indefiniteness, or written description?

Requires claim wording to identify indefiniteness triggers and written-description support needs.

Which prior art patents and non-patent literature most threaten US 10,920,211?

Prior art selection is claim-dependent and not inferable from the patent number alone in this context.

Is US 10,920,211 part of a family with broader continuation or narrower divisional coverage in the US?

Family mapping requires bibliographic and prosecution data (publication/application numbers, continuations/divisionals, claim amendments). None is provided here.

How does US 10,920,211 compare with nearby patents in the same therapeutic area or delivery modality?

Cannot compare without knowing what the patent claims cover.

What generic entry risks exist for products potentially practicing the claims of US 10,920,211?

Entry risk requires mapping to an actual commercial drug or category and knowing what practicing the claims requires.

What formulations are protected by US 10,920,211?

Formulation protection is claim-dependent.

What method-of-use patents overlap with US 10,920,211?

Method-of-use overlap is claim-dependent.

What Orange Book status is associated with US 10,920,211?

Orange Book mapping requires the associated listed drug and NDA/ANDA linkages, which are not provided.

Has US 10,920,211 been asserted in patent litigation or covered by PTAB challenges?

Litigation/PTAB analysis depends on known case dockets or petition identifiers, which are not included.

When does exclusivity end for US 10,920,211 protected subject matter?

Exclusivity and patent term require filing date, priority claims, patent term adjustments, terminal disclaimers, and any regulatory exclusivity events. None are provided.

Key Takeaways

  • A complete analysis of US 10,920,211 cannot be completed without the actual claim text that the prompt references but does not include.
  • No reliable scope, validity, design-around, or landscape conclusions can be produced under the constraints.

FAQs
