Coverage

What does this patent actually cover?

This patent describes a gel that delivers nicotine through the skin or mucosal surfaces. It uses a specific solvent system containing a mixture of water, alcohol, a monoalkyl ether of diethylene glycol, and a glycol. By keeping these ingredients in precise ratios, the gel prevents the nicotine from crystallizing on the skin surface, which helps it absorb more effectively. It also reduces the chance of the medicine rubbing off onto clothing or other people.

The gap

What does this patent NOT cover?

  • Does not cover solid nicotine patches that use an adhesive backing to stay on the skin
  • Does not cover nicotine delivery systems that rely on inhalation or combustion
  • Does not cover formulations that lack the specific ratio of diethylene glycol ether to glycol
  • Does not cover occlusive delivery systems that seal the skin off from the air

These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.

What made this novel

The innovation lies in the specific solvent ratio that balances skin penetration with the physical stability of the gel, preventing the drug from turning into solid crystals on the skin surface.
