Common Mistakes in Patent Claims: How to Correctly Describe Data Transmission

29 / 1 / 2025

When drafting patent claims, precision in language is crucial to ensure that the invention is accurately described and protected. A single misplaced word can alter the entire meaning of a claim, potentially leading to misunderstandings or even legal disputes. One common mistake that often slips under the radar is the improper use of the word "include."

The Problem with «Include»

Imagine you are working on an invention related to Navigation, where a user’s phone needs to transmit its location to a server. Many patent attorneys might draft a claim that reads: «transmit a message that includes a location.» At first glance, this seems straightforward. However, the problem arises when «include» suggests packaging or containing something tangible.

Why «Include» Falls Short

A location isn’t a physical entity that can be packaged and sent. Your phone can’t transmit your office space to a server. Instead, what’s being transmitted is data that represents or references that location. Using «include» in this context implies the impossible—transmitting a physical place.

Correcting the Mistake

To fix this issue, you can use two powerful words: «indicate» and «identify.» These words help clarify that the message contains a reference to the location rather than the location itself. Here are some corrected versions of the claim:

Transmit a message that identifies the location.

Transmit a message that indicates the location.

Transmit a location identifier.

Transmit an indication of the location.

Each of these alternatives clearly conveys that the message contains a reference to the location, which is a piece of data that can be transmitted.

Why Precision Matters

Using precise language in patent claims is essential for several reasons:

Clarity: Clear and unambiguous claims reduce the risk of misinterpretation by examiners, competitors, and courts.

Scope: Accurate claims ensure that the scope of protection is correctly defined, preventing others from infringing on your invention.

Enforceability: Well-drafted claims are easier to enforce in legal proceedings, providing stronger protection for your intellectual property.

Conclusion

The next time you are describing a message, information, or data that includes something, take a moment to verify whether that thing can actually be included in the message. If it cannot, use the words «identify» or «indicate» to describe the data more accurately. By doing so, you can ensure that your patent claims are clear, precise, and legally robust.

By avoiding common mistakes and using precise language, you can strengthen your patent applications and better protect your inventions.

Some Thoughts about Current U.S. Patent System

The U.S. patent system, once a driving force behind technological advancement, is now widely seen as faltering. To restore its vitality, experts argue that a dedicated, long-term effort is needed to address its shortcomings. This discussion focuses on pinpointing the root causes of the system's decline and offering actionable solutions to reinvigorate it.

In its heyday, particularly during the 1980s, the patent system thrived. The U.S. Patent and Trademark Office (USPTO) successfully reduced its backlog, cutting the average pendency time to just 18 months.
