Creating Better Applications Through Patent Strengthening

By Martin Bijman
June 20, 2018

Patent strengthening is the term we use to refer to the process of achieving the greatest potential for value from a patent during the prosecution – before a patent is even granted.

Events along the prosecution process create multiple windows of opportunity for strengthening a portfolio. Decisions are based on indications of market adoption using evidence from specialized technical analysis. and subject matter experts who examine products in the market that potentially use your teaching and proposed claims.

There are four key factors to consider during the prosecution process that can identify strengthening opportunities:

  • Adoption of the innovation in the marketplace
  • Identifying additional innovations to pursue
  • Tuning applications to a company of interest
  • Abandoning applications with concerns

Adoption of the innovation in the marketplace

Prosecution teams typically pursue numerous inventions at once, which is beneficial as it generally ensures the growth of a portfolio. Filtering out inventions that are unlikely to prove valuable is highly desirable at this stage – portfolio managers can save a great deal of time and money by focusing on those applications that are more likely to have sufficient future licensing potential and returns.

Determining which inventions to focus on isn’t always obvious, but a strong indicator of the potential value in an application is market adoption. If you can find products that use the innovation you described in an application, that is indication of market adoption, and indication that your patent (once granted) will be of value.

In this instance, strengthening provides a filter function – enabling you to zero-in on claims that are more worthwhile based on your business goals. While there isn’t an immediate financial reward, it does mean you have identified a real asset that can be tracked and prioritized.

Further, you may wish to focus on adoption by a company of interest that you are watching. In this way, applications that may be applicable to the products of the company of interest can be prioritized by the prosecution team, including evidence of use, so that once they are granted they are immediately ready to add to a potential negotiation.

Identifying additional innovations to pursue

A claim focuses on a single innovation, yet there may actually be several innovations described in a single application. At the time of filing, your focus is on the primary invention, but throughout the prosecution it may become clear that an alternate – and potentially more valuable –  innovation is also encapsulated in the teaching.

If other innovations are identified, they can be pursued. The primary claim can still be pursued, or it can be de-prioritized or abandoned. In this case, strengthening is the process of uncovering additional innovations in a claim and prioritizing which innovation(s) to pursue, based on evidence found in products introduced to market after your priority date.

Another ongoing opportunity to identify additional innovations is in the three-month window between allowance of a claim and its subsequent granting as a patent. Companies will have an ongoing list of teachings to review to ensure that other valuable innovations in the teachings that may be getting adopted in the market are pursued for further claims.  Through ongoing surveillance of this list, you can ensure your innovations are well harvested, and that claims are made for those that are aligned with market adoption.

Tuning applications to a company of interest

The term “company of interest” can apply in an assertive or defensive capacity.   Recent success in a market by you or your competitors is the trigger for you to prepare to defend against assertion, or for you to prepare to assert against an infringer.

In addition to reviewing the patents you hold, exploring and identifying which of the applications you have in progress that are potentially used by the company of interest can bolster your negotiating position.

Finding applications of interest against a specific company allows your prosecution team to prioritize and tune your claims to better target the available evidence for that company.  Quite often this activity harnesses continuations, which are very often launched for your more valuable applications, and also the prosecution of continuations occurs several more years after your priority date, making it more likely that products using the innovations have entered the market.

Abandoning applications with concerns

Prosecution teams like to get the best possible claims for their applications. But consider a claim with the following types of concerns:

  • The market is moving in a different direction and the claim will never be used
  • It cannot be proven that the claim is being used
  • The innovation may not have any practical or economic value
  • The claim could be for an invention that’s getting many tiny refinements
  • The marketplace may already be overcrowded
  • Your company may no longer be pursing this market
  • New prior art may have been recently discovered
  • The claim construction may have become challenging in response to recent office actions

The risk of pursuing a claim with the type of concerns noted above is that you will spend too much time, effort, and money investing in patents that may have a low return. The way to mitigate this risk is to routinely examine claims to ensure they are not associated with these types of concerns. This provides you the opportunity to make your portfolio stronger by focusing on applications that may have a higher return-on-investment.

Consider, too, the office action process. The Examiner will read the claim and send a response – an office action – requiring the claim to be modified. It’s an iterative process and most claims take two cycles to refine before they’re granted. After the second action there’s greater urgency to get it right, or you risk getting a final rejection from the Examiner.  It may be beneficial to pursue surveillance of market adoption and claim concerns during your office action cycles.

Stronger patents, stronger portfolio

By optimizing each application you pursue, you ensure that resulting patents carry the greatest potential to achieve the greatest value. And by creating a collection of valuable patents, you increase the overall value and strength of your portfolio.

    It’s good to prove the evidence of use for a patent application before it was granted, the EOU may be a standard claim chart, or analyze report. And so patent applicant can have the opportunity to adjust the claim scope to get closer to the target market product.
    But the method to identify the evidence of use is somewhat not so easy for patent prosecution members, they should rely on the support of inventor or technologist to confirm whether the invention have been implemented. Some invention especially such as circuit algorithm, semiconductor microstructure, and need professional analyze and reverse engineering.
