Addressing the Unique Challenges in Nanotech Patenting

Nanotechnology, given its intricate nature and relatively nascent stage in various industries, presents unique challenges that startups need to be aware of and address proactively.

The Ambiguity of Nanoscale

One of the primary challenges in patenting nanotech innovations lies in the very definition of ‘nanoscale.’ Given that nanotechnology deals with structures typically between 1 nm to 100 nm, defining the specific size, composition, and structure becomes crucial. In your patent application, it’s essential to be as descriptive and precise as possible, shedding light on how the nanoscale contributes to the novel functionality of the food packaging.

Overcoming the Obviousness Hurdle

As mentioned previously, for an invention to be patentable, it should not be an obvious iteration of existing technology. Given the rapid pace of advancements in nanotechnology, it can be challenging to delineate that a specific innovation isn’t just a minor, obvious tweak, but a genuine leap. This distinction becomes even more crucial in the food packaging sector, where the practical application of the innovation – like extended shelf life or improved freshness – should be evident and non-trivial.

Collaborative Efforts and Joint Ventures

The interdisciplinary nature of nanotechnology often necessitates collaborations, bringing forth additional considerations.

Joint Patents and Shared IP

When startups collaborate with research institutions, universities, or even other companies, the resultant innovation may be a shared effort. In such cases, understanding and defining the ownership of the intellectual property becomes essential. Drafting clear agreements that delineate ownership percentages, rights to commercialize, and responsibilities can prevent potential disputes down the line.
