You are months into tooling a new toy, or you have units already on the way, and someone points you to a competitor’s patent that appears to cover it. Sometimes a buyer’s compliance team flags it. Sometimes a letter arrives. The launch date does not move for any of that, and now there is a legal question sitting on top of a production schedule.
An up-front disclaimer. Questions like this are fact-specific and the answers depend on the particular patent, the particular product, and where you are in the calendar. Nothing here is legal advice and no one should rely on it as legal advice. These are general comments on how we typically approach the problem.
There are usually more options available than people expect, and several of them are faster than litigation.
Start with the claims
The scope of a patent is set by the numbered claims at the end of the document. The title, the abstract, and the drawings are not what you are measured against, and a great deal of unnecessary alarm can come from reading those instead of the claims.
For a utility patent, infringement of a claim typically requires that every element of that claim be present in your product. If your toy leaves out one element, that claim is generally not literally infringed. This is why a patent that sounds like a direct hit on its face often turns out not to reach the product once someone works through the claim language element by element.
Design patents work differently. There the question is closer to whether an ordinary observer would find the two designs substantially the same. Many toy products have both kinds of patents pointed at them, so both analyses may be needed.
Confirm the patent is still in force
This step is quick and it resolves more situations than you would think. Patents expire, and they also lapse when maintenance fees go unpaid. A patent that is no longer in force is not something you need to design around.
Checking the current status and the remaining term is inexpensive and worth doing before anyone spends money on a deeper analysis.
Design around it
If a claim does reach your product, the next question is what it would take to fall outside it. Because infringement of a utility claim typically requires every element, removing or substantively changing one element can be enough.
Toys are often good candidates for this. There is usually more than one mechanism that produces a given play pattern, and the ornamental appearance can frequently be changed without hurting the product. The constraint is timing rather than engineering. A design-around identified before tooling is locked may be a modest change, and the same change identified after tooling may be prohibitively expensive.
So it is best to review design-arounds early rather than waiting to see whether a dispute becomes serious.
Challenge whether the patent should have issued
A patent is presumed valid, but examiners work with limited time and an imperfect view of what already existed. If there is prior art the examiner never saw, the patent may not hold up.
One route is an inter-partes review, or IPR, at the Patent Office. In practice an IPR is more like full-blown patent litigation than an administrative filing. There are briefs, expert declarations, depositions, and a hearing, and it is decided by administrative patent judges. The grounds available are limited to prior patents and printed publications.
Two features of an IPR matter a great deal for planning. First, there is a deadline. If you have been served with a complaint for infringement of the patent at issue, the window to file an IPR petition typically closes one year after service. Second, there is estoppel. If the challenge goes to a final written decision and does not succeed, you typically give up the ability to raise those same invalidity arguments, and arguments you reasonably could have raised, in district court later.
Ex parte reexamination is another route. It is generally less expensive and carries different consequences, though you have far less control over how the proceeding unfolds once it begins. Which route fits depends on the strength of the prior art, the posture of the dispute, and what you are trying to accomplish.
License it
A license is sometimes the most direct path to getting the product on the shelf, particularly when the patent holder is not a direct competitor or when the product is one piece of a larger line.
The position you negotiate from is built earlier. Understanding claim scope and knowing whether there is credible prior art changes what a reasonable royalty looks like, so the analysis is worth doing before the conversation rather than during it.
The timing problem in toys
Toy products typically run on a compressed calendar: tooling, trade show commitments, retailer buy dates, and in many cases a short selling season. None of the options above move at that speed once a dispute is already underway.
A claim analysis and a prior art search take weeks, not days. An IPR proceeds over roughly a year and a half from petition to decision. District court litigation takes considerably longer than that. If the first serious review happens after a complaint is filed, the calendar is already working against you, and the one-year IPR window is running at the same time.
The practical answer is to review the patents that concern you while the product is still in development.
Where to start
When a client brings us a patent that appears to be in the way, the sequence we typically follow is a claim-by-claim review of that patent against the product, a status and term check, and a prior art search where the claims do appear to reach. What comes out of that is a clear picture of whether you have an infringement problem, and if you do, which of the options to solve it is most practical.

Frequently asked questions
A competitor’s patent looks like it covers my toy. Does it?
Not necessarily. The numbered claims define the scope of a patent, not the title, abstract, or drawings. Infringement of a utility claim typically requires that every element of that claim be present in your product, so a patent that appears to cover a product on its face often does not once the claims are reviewed element by element, with ambiguous claim terms construed in view of the rest of the patent.
How long do I have to file an IPR petition?
If you have been served with a complaint for infringement of that patent, the window to file an inter partes review petition typically closes one year after service. Waiting to see how the litigation develops can close that option.
Is an IPR a faster alternative to litigation?
An IPR is quicker than most district court cases and typically runs about eighteen months from petition to final written decision, but it is a substantial proceeding with briefing, expert declarations, depositions, and a hearing. It is closer to litigation than to a filing.
What happens if I lose an IPR?
If the proceeding reaches a final written decision and the challenge does not succeed, you typically cannot raise those same invalidity arguments, or arguments you reasonably could have raised in the IPR, in district court afterward. That estoppel is a significant part of the decision about whether to file an IPR petition.
Can I just change the product instead?
Often, yes. Because infringement of a utility claim typically requires every claim element, changing or removing one otherwise-claimed feature can be enough to avoid infringing that claim. Design-arounds are less disruptive the earlier they are identified.
Should I get an opinion of counsel?
A written opinion on infringement or validity can be worth obtaining when a company plans to proceed with a product after learning of a patent. Whether it makes sense in a given situation depends on the facts and is worth discussing directly.
