How to build an IP strategy instead of filing one-off patents
An IP strategy replaces one-off patents with a repeatable set of decisions: map the product roadmap and competitors first, decide per invention whether to patent, keep as a trade secret, or publish defensively, set a written filing rule and target jurisdictions, and review the portfolio against the roadmap at every funding round. The output is patent families that cover where the business is going, not where it has been.
- Funding effect: startups holding both patents and trade marks at seed or early stage are up to 10.2 times more likely to secure funding (EPO and EUIPO, 2023)
- Priority window: a first filing fixes the worldwide priority date for 12 months under the Paris Convention (International filing strategy for startups)
- Grant timeline: around 20 months to first office action and about 26 months total pendency at the USPTO, so claims must anticipate the product two years out (USPTO Patents Dashboard)
- Publication: patent applications publish 18 months from the earliest priority date, which is why undetectable inventions are often better kept as trade secrets (WIPO PCT)

The one-off patent problem
Most first patents are filed for a reason outside the technology: an investor asked, a competitor filed, a conference is coming. The application claims what existed that month. Two years later it grants, the product has changed, and the company has a granted patent on a prototype and no protection on what it sells. Repeating that three times is not a strategy, it is three expensive accidents.
Start from the roadmap and the competition
Write down what the company will ship in the next 24 months and which parts of it are hard: the mechanism competitors would need to copy, the manufacturing step that makes it work at scale, the data or model that makes it better over time. Then list the two or three competitors who matter and what they have filed. The intersection, what you are building that they would want, is where patents earn their cost.
Pick the instrument, not just the patent
- Patent when the invention is visible in the product or its documentation, hard to design around, and on the roadmap. A patent publishes the invention, so it only makes sense when competitors could find it anyway
- Trade secret when the invention lives inside a process or a model that cannot be reverse-engineered from the product, and the company can actually keep it secret
- Defensive publication when the invention is real but not core: publishing it makes it prior art so nobody else can patent it, at almost no cost
Write the rules once
Three written rules turn a strategy into an operating system. A filing rule: what a disclosure must satisfy to be filed. A jurisdiction rule: which two to four markets get filed by default and what would change that. A review rule: every funding round and every major roadmap change, the portfolio is mapped to products and pruned. Rules remove the case-by-case argument that stalls most patent decisions.
Design families, not filings
A strong position is usually a small number of families that grow: a first application on the core mechanism, continuations or divisionals as the product develops, and separate families on the method and on the next generation. Terminology should be consistent across the family so each new claim inherits the strength of the last. This is also what investors read in due diligence: whether the portfolio was built on purpose.
What most companies get wrong
- Counting patents: the metric is roadmap coverage, not number of filings
- Outsourcing the strategy to the law firm: attorneys can tell you what is patentable, not what matters to the business
- Never pruning: maintenance fees on legacy patents are strategy debt
- Treating trade secrets as free: a trade secret without access controls and documentation is just an unpatented invention
How Lightbringer supports strategy, not just filing
Lightbringer is the AI-native patent service for tech companies: patents drafted with purpose-built AI, reviewed and filed by Lightbringer's own patent attorneys, for one flat fee per application.
Because disclosures, drafting, filing, and portfolio data sit in one platform, the roadmap map is a working view rather than a slide made once a year, and Lightbringer's attorneys advise on what to patent, keep secret, or publish as part of the service. Flat pricing, the Starter plan at $7,200 per patent application per year with official fees separate, means a strategy can be budgeted as a programme. More than 200 deep tech companies across the US and EU use it.

Frequently asked questions
A patent protects one invention as claimed. An IP strategy is the set of decisions about which inventions to protect, where, in what form, and how they connect to the product roadmap and the competition. The strategy tells you which patents to file; the patents are the output.
There is no number. A strategy is defined by coverage of the roadmap and the competitive position, not by count. Three families that cover the core mechanism, the manufacturing method, and the next product generation can be stronger than 15 filings on features.
No. Patents publish the invention, so anything competitors cannot detect or reverse-engineer may be better held as a trade secret. Inventions that are not on the roadmap can be published defensively so nobody else can patent them. The strategy is choosing the right instrument for each.
At every funding round and every major roadmap change, at minimum annually. Each review maps every asset to a product, drops what no longer serves the business, and identifies roadmap items with no coverage before they ship.
