As your company expands into international markets, your patent strategy may need to expand with it. A patent that protects your technology in the United States generally won't provide the same protection overseas, raising an expensive question for companies selling across multiple countries: how many of those markets actually need patent coverage?
The answer isn't necessarily all of them. While patents are territorial, filing everywhere you have customers isn't always the best use of your patent budget. For most companies, the better approach is to prioritize countries where patent rights could have the greatest commercial impact, which may include markets where you don't currently sell anything at all.
That means looking beyond your current sales footprint to consider where competitors operate, where products are manufactured, and where patent protection would give your company meaningful leverage.
What happens if you sell in a country where you don't have a patent?
You don't need to own a patent in a country to sell your product there. A patent gives you the right to exclude others from using your patented invention in the jurisdiction where it's protected, but it doesn't give you permission to sell your own product.
That distinction matters for international patent strategy. Even if your company holds a U.S. patent, you could still infringe another company's patent or other intellectual property rights when selling your product overseas. This is why patent protection and freedom to operate are separate considerations.
Without a patent in a particular country, you generally won't be able to prevent competitors from using your invention there based on your patent rights elsewhere. However, that doesn't necessarily mean competitors can sell infringing products in your protected markets.
For example, suppose your company holds a U.S. patent for a manufacturing technology, but no corresponding patent in China. A competitor might be able to use that technology in China without infringing your U.S. patent. But if it tries to import products covered by your patent claims into the United States, you may still have grounds to take action.
The question, then, isn't whether you can afford to leave certain countries unprotected. It's whether the additional protection in each country is valuable enough to justify the cost of obtaining and maintaining those patent rights.
How should you decide which countries are worth patenting in?
When it comes to international patent protection, the 80/20 rule is a useful starting point. For many companies, a relatively small number of jurisdictions account for the majority of their commercial opportunity. That's why major jurisdictions such as the United States, China, Japan, South Korea, and India, along with European patent protection, often feature prominently in international filing strategies.
Protecting those markets can provide substantial coverage without the expense of filing patents in every country where they have customers. Here are four questions to help prioritize them.
1. How important is the country to your current and future revenue?
A country that accounts for a significant portion of your sales is an obvious candidate for patent protection. If competitors could freely copy your technology and compete against you in that market, the financial consequences could justify the expense of obtaining local patent rights.
But current revenue shouldn't be your only consideration. Suppose your company generates 80% of its revenue in the United States today, with relatively small sales in Japan. If Japan is central to your long-term expansion strategy, Japanese patent protection might still be worth pursuing before your revenue there becomes substantial.
It's worth considering not just where your revenue comes from today, but where you reasonably expect the invention to generate commercial value over its useful life.
2. Where are your products and competing products manufactured?
Manufacturing locations can be just as important as sales markets, and sometimes more important.
Imagine a U.S. hardware company that sells in North America, Europe, and Australia. Its competitors manufacture most of their products in China before exporting them to those markets. Even if the company has few customers in China, Chinese patent protection might be strategically valuable. Depending on the patent claims and circumstances, it could let the company challenge infringing manufacturing activity at its source rather than relying solely on patent enforcement in individual destination markets.
This is particularly relevant when an industry has a concentrated manufacturing base. If the companies capable of producing a competing product are clustered in one or two countries, protecting those jurisdictions may offer more practical leverage than filing across every country where the finished products are sold.
Of course, manufacturing-country protection is no substitute for protecting major sales markets. A competitor may be able to manufacture elsewhere, and the remedies available against manufacturing and export activities differ by jurisdiction.
3. Where are your most important competitors?
A country might represent a relatively small portion of your own sales but still be commercially important because a major competitor is headquartered there, operates significant R&D facilities there, or plans to enter that market.
For example, a U.S. industrial technology company might view Germany as a priority jurisdiction because several of its largest competitors operate there. The value of German patent protection could extend beyond the company's immediate German revenue, particularly if the patents cover technology those competitors are likely to commercialize.
The same consideration can apply to potential licensing partners or acquirers. Patent rights in jurisdictions that are commercially important to those companies may make your portfolio more relevant to a future transaction.
That doesn't mean you should automatically file wherever a potential competitor or acquirer has an office. The useful question is whether enforceable rights in that jurisdiction would give your company meaningful commercial leverage.
4. Would you realistically enforce a patent there?
Obtaining a patent is only part of the investment. If a competitor infringes it, your company may need to investigate the activity, establish infringement, and pursue legal remedies in the relevant jurisdiction. That can be expensive, particularly if the potential financial harm is relatively small.
Before adding a country to your filing strategy, consider:
- The strength and predictability of local patent enforcement: How effectively can patent owners assert their rights, and what remedies might be available?
- The cost of enforcement relative to the market opportunity: Would the potential commercial value justify the expense of pursuing an infringer?
- Your ability to identify infringement: Would you be able to determine whether competitors are using the patented technology, particularly if it involves an internal process or system that isn't visible in a finished product?
There are good reasons to obtain patents that you never expect to litigate. Patents may support licensing discussions, deter competitors, or make a portfolio more attractive to potential acquirers.
However, those benefits should still be grounded in a plausible commercial use for the rights. Simply adding another jurisdiction to your portfolio doesn't necessarily create meaningful value.
When do you have to decide which countries to file patents in?
Deciding where to pursue international patent protection can be difficult when your company is still figuring out which markets will matter most. Fortunately, you don't necessarily have to commit to every country when you first file a patent application.
The Patent Cooperation Treaty (PCT) lets you preserve the option to seek patent protection across multiple countries while deferring many of the costs and decisions of individual national filings.
A PCT application doesn't grant an international patent. Instead, it establishes an international filing process, after which you can pursue patents in the individual countries or regions you select. In most jurisdictions, you have approximately 30 months from your earliest priority date to enter the national or regional phase, although some countries allow longer and others have different deadlines.
For a growing company, that additional time can be valuable. You might initially expect Europe to be your largest international market, only to discover stronger demand in Asia. Or a competitor might begin manufacturing in a country that wasn't previously a priority. The PCT process can give you more time to assess those developments before committing to specific jurisdictions.
However, the PCT doesn't let you keep your international filing options open indefinitely. Once the applicable deadlines pass, you generally lose the ability to pursue protection through that application in countries where you haven't entered the national or regional phase, subject to limited exceptions.
This makes it important to revisit your international filing priorities before those deadlines arrive, even if your expansion plans are still uncertain. The goal is to preserve protection where it's likely to matter without committing to unnecessary filings before you have enough information to justify them.
