Imperium IP vs LegalZoom: Trademark Screening Compared
These two tools do different jobs, and comparing them on price alone gets founders in trouble. LegalZoom files trademark applications. Imperium IP tells you whether the name you picked is worth filing in the first place. If you file a name that collides with three live registrations, you have not saved money - you have bought a refusal, and USPTO filing fees are non-refundable.
Imperium IP is a screening tool, not a filing service and not a law firm. It tells you how risky a name looks before you spend money on it. What you do next - file yourself, use a filing service, or hire a trademark attorney - is your call, and the report is built to hand over.
What LegalZoom is
LegalZoom is a large online legal services company that files trademark applications for you, with attorney-led packages and a free basic search tool at the top of the funnel.
What LegalZoom does well
- Files the application for you, with attorney-led packages, so you are not learning USPTO forms at midnight.
- Handles minor USPTO correspondence on your behalf inside their paid packages.
- A recognizable, established brand with a large support operation - genuinely reassuring for a first-time filer.
- Bundles trademark work with entity formation and other legal services, which is convenient if you need all of it at once.
Imperium IP vs LegalZoom, side by side
| Dimension | Imperium IP | LegalZoom |
|---|---|---|
| What the product is | Screening and risk analysis. Does not file. | Filing service. Search is the front end of a paid filing package. |
| What you get back | A 0 to 100 Similarity Index with the conflicting marks listed and ranked by exact, contains, and phonetic similarity - so you can see why the score is what it is. | A search result and a recommendation to proceed to a paid package. Depth of analysis depends on the tier you buy. |
| Reasoning shown | The scoring algorithm is deterministic and published - same input, same score, and the weighting is documented. | Proprietary. The reasoning behind a go/no-go is not exposed to you. |
| Phonetic and sound-alike marks | Surfaced by default and weighted in the score. | Depth varies by package; a basic free search leans toward direct matches. |
| Cost to screen a name | Free. Search and Similarity Index cost nothing. | Free basic search; meaningful analysis is bundled into paid filing packages. |
| Screening several candidate names | Run as many as you want and compare scores side by side before choosing. | Packages are oriented around the mark you have already chosen. |

Questions
Can Imperium IP file my trademark like LegalZoom does?
No. Imperium IP does not file trademark applications and is not a law firm. It screens names and produces a Preliminary Trademark Report. Once you know a name is worth pursuing, you file it yourself through the USPTO, use a filing service, or hire a trademark attorney.
Is a free trademark search enough before I file?
A free search is a starting point, not a clearance. Most free tools emphasize direct matches, but the USPTO can refuse a mark that merely sounds like an existing one or creates a similar commercial impression. Screening should cover phonetic and similar marks, and even then, a licensed trademark attorney must evaluate before you file.
Should I use both?
That is the common path. Screen candidate names with Imperium IP, pick the one with the lowest conflict risk, then file through whichever service or attorney you prefer. Screening first means you are not paying filing fees on a name that was never going to survive examination.
Does a low Similarity Index mean my trademark will be approved?
No. A low score means the automated screen did not surface obvious conflicts in USPTO data. It does not account for common-law rights, unregistered use, or an examining attorney judgment call. Clients have been sued over marks that passed automated knockout searches. A licensed attorney must evaluate before you file, invest, or adopt a mark.
