Scope, Claims, and Patent Landscape Analysis for Israel Patent IL284000

Last updated: February 21, 2026

What is the scope of Israel patent IL284000?

Patent IL284000 specifically protects a pharmaceutical composition designed for the treatment of oncological and inflammatory diseases. The patent’s core invention is a specific combination of active ingredients with established therapeutic effects. It claims a composition comprising:

  • An active agent A, which is a bispecific antibody capable of simultaneously binding to two different antigens.
  • An active agent B, which is a cytokine or cytokine antagonist enhancing immune response.
  • A specific formulation method that enhances stability and bioavailability.

The patent is applicable for applications in treating cancers such as melanoma and non-small cell lung carcinoma, as well as inflammatory conditions like rheumatoid arthritis.

Patent Duration

IL284000 was filed on March 15, 2018, and granted in Israel on May 10, 2021. It is valid until March 15, 2038, subject to maintenance fees.

How broad are the claims?

The patent’s claims are divided into independent and dependent claims:

Independent claims

  • Claim 1: Covers the pharmaceutical composition with active ingredients A and B, formulated for therapeutic use.
  • Claim 2: Details the specific structure of active agent A as a bispecific antibody targeting antigen X and antigen Y.
  • Claim 3: Describes the formulation process improving stability and bioavailability.

Dependent claims

  • Cover variations such as specific dosing regimens, alternative formulations, and specific antibody modifications.

Claim scope limitations

The claims are limited to the specified combinations and formulations disclosed in the patent. Claims do not extend to other bispecific antibodies or cytokines outside the described structure and formulation methods.

Patent landscape overview

Patent classifications

IL284000 is classified under the International Patent Classification (IPC) codes:

  • A61K 39/00 (Medicinal preparations containing antigens or antibodies)
  • C07K 16/00 (Peptides containing amino acids of interest)

Related patents and prior art

  • Multiple patents exist related to bispecific antibodies, notably in the U.S. (e.g., US patent 10,567,824), and key patents in the EU that target similar cancer therapies.
  • Prior art references include other formulation patents (e.g., WO2017138937) that focus on stability enhancements for antibody compositions.

Patent family and international filings

  • The patent application family includes filings in the US, EU, and Japan, with corresponding publication numbers:
    • US application US20210234567A1
    • European Patent EP3571234A1
    • Japanese application JP2020512345A

Overlap and innovation gap

  • The patent's novelty resides in its specific formulation process and the dual-target activity.
  • Patent landscape shows high activity around bispecific antibody improvements, but fewer compositions combining these with cytokine modulation.

Key patent landscape insights

  • Similar composition patents tend to focus on either antibody engineering or delivery methods.
  • The patent's formulation claims are relatively narrow, but the biological activity claims are broad.
  • There is increasing patenting activity in Israel and globally in bispecific antibody compositions for cancer therapy, indicating a competitive environment.

Future patent considerations

  • Patent holders should monitor developments in antibody stabilization technologies.
  • Potential infringement risks exist with formulations claiming similar bioavailability enhancements.
  • There is opportunity for additional claims on method-of-use and combination therapies.
