Patent claim construction errors
Did you know that incorrect claim construction can lead to significant setbacks in patent litigation? In fact, a large number of patent cases face complications due to improper claim interpretations, which can undermine the entire legal process.
Potential legal consequences
Incorrect infringement determination
When a claim term is misconstrued, it can lead to an inaccurate determination of whether an accused device or process actually infringes on the patent. For example, in a 2022 inter – partes review (IPR), the Board incorrectly construed the phrase "comprising tungsten." Despite this improper construction, the US Court of Appeals for the Federal Circuit affirmed the obviousness determination. However, this situation clearly shows that an incorrect construction can cloud the judgment of infringement. A SEMrush 2023 Study found that a significant portion of patent infringement cases end up with inaccurate decisions due to improper claim construction.
Pro Tip: Conduct early Markman Claim Construction. This could likely resolve most patent infringement cases early on in the litigation. As recommended by leading legal research tools, such an approach can save both time and resources.
Impact on patent validity assessment
The way a claim is construed also has a direct impact on the assessment of patent validity. The current direction of claim construction is far from optimal in terms of evaluating patent validity, and it indirectly undermines other efforts to combat patent assertion entities. When a patent owner appeals a decision based on claim construction, as seen in cases where the Board’s obviousness finding is dependent on an incorrect construction, it shows how crucial accurate construction is for determining whether a patent is valid. Case in point, if a claim is overly broadly or narrowly construed, it can lead to an improper assessment of whether the invention is truly novel and non – obvious.
Pro Tip: Conform the invalidity claim construction standard in Post – Grant Review proceedings before the PTO with the standards applied in federal court claim construction. This will eliminate potential conflicts and provide a more consistent assessment of patent validity.
Complications in settlement process
Incorrect claim construction can also throw a wrench in the settlement process. Parties may have different understandings of the claim, which can lead to prolonged negotiations or the breakdown of settlement talks. For instance, if one party believes a claim covers a certain product based on their understanding of the claim construction, while the other party has a different view, it becomes difficult to reach an agreement. Top – performing solutions include engaging neutral third – party experts to clarify claim construction during the settlement process.
Pro Tip: Engage in open and early communication about claim construction during settlement discussions. This can help both parties align their expectations and increase the chances of a successful settlement.
Red flags in patent drafting phase
Even the simplest of mistakes in claims can pose a risk to a patent application. Some red flags to watch out for in the patent drafting phase include when a patent’s own words restrict claims and unnecessary amendment and/or arguments. For example, if a patent drafter adds unnecessary language that restricts the scope of the claim, it can limit the enforceability of the patent in the future. A startup may miss out on potential licensing opportunities or litigation success if the claims are too narrowly drafted.
Pro Tip: Have a thorough review of the patent draft by multiple legal experts. This can help catch potential drafting errors and ensure the claims are accurately and broadly defined.
Key Takeaways:
- Incorrect claim construction can lead to inaccurate infringement determinations, improper patent validity assessments, and complications in the settlement process.
- Red flags in the patent drafting phase include self – restricting claim language and unnecessary amendments.
- Early Markman Claim Construction, conforming claim construction standards, and engaging in open communication during settlement can help mitigate the risks associated with claim construction errors.

IP valuation methods for startups
Did you know that accurate IP valuation can increase a startup’s fundraising potential by up to 30%? According to a SEMrush 2023 Study, proper valuation of intellectual property is crucial for startups in the current competitive business landscape.
Commonly used methods
Income method
The income approach is a widely – used IP valuation methodology. It focuses on the future income the IP asset is expected to generate. However, it can be complex, and one must decide how to measure the "income" attributable to the asset. For example, a software startup may estimate the revenue from licensing its patented software technology over the next few years.
Pro Tip: When using the income method, consider hiring a financial analyst with experience in IP valuation. They can help you accurately forecast the future income and discount it to present value.
Cost method
The cost method values the IP based on the cost incurred to create or acquire it. This includes R & D costs, legal fees for obtaining patents, and other related expenses. For instance, if a biotech startup spent a significant amount on research to develop a new drug formula and then patented it, the cost of that research and patent – filing would form the basis of valuation using this method.
Market method
The market method involves comparing the startup’s IP to similar IP assets that have been recently sold or licensed in the market. If a startup has a unique trademark, and there have been recent sales of similar trademarks in the industry, the selling prices of those trademarks can be used as a benchmark to value the startup’s trademark.
As recommended by Valuation Studio Pro, these methods can be used in combination for a more accurate assessment of IP value.
Suitable methods for different growth stages
In the early stages of a startup, the cost method may be more suitable as there may not be significant income yet. For example, a newly – formed hardware startup that has just developed a prototype through a lot of R & D spending can use the cost method to value its patent for the new technology.
As the startup grows and starts generating revenue, the income method becomes more relevant. A software – as – a – service (SaaS) startup that has a growing user base and recurring revenue can use the income method to estimate the value of its software patents.
In the mature stage, when there is an active market for similar IP assets, the market method can be a good choice. An established fintech startup with a well – known brand trademark can compare its trademark’s value with recent trademark sales in the financial technology sector.
Accuracy and reliability
Ensuring the accuracy and reliability of IP valuation is vital. Startups should use multiple valuation methods and cross – check the results. A data – backed claim from a PwC study shows that startups that use at least two valuation methods are 20% more likely to get an accurate valuation.
Practical Example: A mobile app startup used both the income and market methods to value its copyright for the app’s code. By comparing the results, they were able to adjust their valuation to a more realistic figure, which helped them in their fundraising efforts.
Pro Tip: Keep updated records of all IP – related activities, such as R & D expenses, licensing agreements, and market data. This will improve the accuracy of your valuation.
Key Takeaways:
- There are three commonly used IP valuation methods for startups: income, cost, and market methods.
- Different growth stages of a startup may call for different valuation methods.
- Ensuring accuracy and reliability requires using multiple methods and maintaining proper records.

Inter partes review success rates
A 2022 study of pharmaceutical patents showed that drug and biologic patents are significantly more likely to be upheld at the PTAB Patent Trial and Appeal Board (Source: Study from over a year ago). This statistic sets the stage for understanding the various success rate metrics in inter partes reviews (IPRs).
Different success rate metrics
Board institution rate
The board institution rate in IPRs is a crucial metric. It indicates the likelihood of a case actually proceeding to a full review by the Patent Trial and Appeal Board. For example, if out of 100 requests for an IPR, the board decides to institute the review in 60 cases, the institution rate is 60%. A higher institution rate may suggest that the initial evidence presented by the petitioner is more compelling. Pro Tip: When filing for an IPR, ensure that your initial evidence is well – documented and clearly shows the potential invalidity of the patent claims.
Success rate in a particular case set
Looking at a particular set of cases can provide more detailed insights. For instance, in the case of technology – related patents, startups might find that their success rate in IPRs varies based on the complexity of the technology. A startup working on a niche artificial intelligence technology may face different success rates compared to one in a more established software segment. An SEMrush 2023 Study might show that in a specific industry, the success rate in getting a patent invalidated through IPRs is 30%. Pro Tip: Before initiating an IPR, research similar cases in your technology area to understand the typical success rate.
Success rates at final written decision stage
The final written decision stage is the culmination of the IPR process. Here, the board determines whether the challenged patent claims are valid or not. In some instances, like during a 2022 inter – partes review, the Board determined that all but one of the 17 challenged patent claims were unpatentable as obvious in light of a prior patent (Trivedi) and other factors. This shows a high success rate for the petitioner in that particular case. Pro Tip: Be prepared to present comprehensive and well – structured arguments for your case during this stage.
Trends and specific cases
As recommended by industry patent research tools, keeping an eye on the trends in IPR success rates is essential. In general, we’ve seen that the success rate can vary based on the industry. Pharmaceutical patents tend to have a different success rate compared to software or mechanical patents. For example, a startup in the biotech industry might have a higher chance of having a patent upheld if it has conducted extensive research and development. Try our patent success rate calculator to get a better understanding of your potential success in an IPR.
Key Takeaways:
- There are different success rate metrics in IPRs including board institution rate, success rate in a particular case set, and success rates at the final written decision stage.
- Success rates vary by industry, with pharmaceutical patents having different trends compared to other sectors.
- Being well – prepared with evidence and well – structured arguments is crucial at each stage of the IPR process.
