WHY CHOOSE

Why Choose Sherinian Law as Your Chicago Trademark Lawyer

Trademark disputes and registration issues require careful legal analysis and a practical strategy. Sherinian Law advises Chicago-area businesses, startups, and online sellers on trademark protection, federal registration, and infringement matters. We review each situation individually, explain the available legal options, and help clients make informed decisions about protecting their brands.

Trademark Counsel for Chicago Startups

Approximately 75% of our clients are early-stage startups. Our client experience includes businesses such as Ocient as well as companies at earlier stages of development. We understand the importance of protecting trademarks while businesses are developing products, entering markets, and building brand recognition. Our attorneys provide practical guidance on trademark registration, infringement concerns, and available legal options.

Federal Trademark Litigation Experience

Our attorneys have represented clients in federal trademark litigation, including more than 50 historical Schedule A matters in the Northern District of Illinois. Schedule A litigation is part of our firm's past experience and is not a litigation format we currently offer. For new trademark disputes, we assess the individual facts and discuss potentially appropriate legal remedies, including federal litigation when warranted.

Trademark Registration & Brand Protection

Our attorneys assist clients with USPTO trademark applications, registration-related issues, TTAB proceedings, and federal trademark disputes. We also advise on international trademark filing options, including the Madrid Protocol where applicable. Trademark searches and office action responses are separately scoped and charged as applicable. We explain the proposed legal services, applicable fees, and next steps before beginning an engagement.

Chicago Trademark Attorney Services: Registration, TTAB & Federal Litigation

Federal Trademark Registration & Filing

Our Chicago trademark attorneys assist businesses with preparing and filing federal trademark applications with the United States Patent and Trademark Office (USPTO).

We review the relevant filing requirements, discuss potential registration issues, and help clients understand the application process.

Our Services May Include:

  • Preparation of federal trademark applications.
  • Guidance on trademark classes, descriptions, and application requirements.
  • Preparation and submission of application materials to the USPTO.
  • Trademark searches and clearance reviews when separately requested or recommended.
  • USPTO Office Action responses when required and separately agreed upon.
Service Scope & Fees: Trademark application preparation and filing fees depend on the agreed scope of representation. Trademark searches, written clearance reports, and USPTO Office Action responses may involve additional fees. Applicable USPTO government fees are also explained before filing. Trademark registration is subject to USPTO examination and approval.

Trademark Infringement & Federal Court Litigation

Trademark infringement disputes can affect a company's brand identity, customer relationships, and commercial activities.

Our attorneys evaluate trademark infringement concerns and advise clients on legal options based on the facts of each matter.

Available Legal Approaches May Include:

  • Reviewing alleged trademark infringement and available supporting evidence.
  • Evaluating trademark ownership, priority, and enforceable rights.
  • Advising on cease-and-desist communications and possible negotiated resolutions.
  • Assessing federal court litigation where appropriate.
  • Developing a legal strategy based on the circumstances and objectives of the client.
Our Experience: Our attorneys have experience representing clients in federal trademark litigation in the Northern District of Illinois, including historical Schedule A matters. The firm no longer offers the Schedule A multi-defendant litigation format described in those historical matters. Current disputes are evaluated individually to determine appropriate legal options.

Amazon Seller & E-Commerce Brand Protection

Online sellers may face trademark infringement, counterfeit listings, and unauthorized use of their brands across e-commerce platforms.

We advise businesses on trademark protection and potential enforcement options involving online marketplaces, including Amazon and other e-commerce platforms.

Our Approach May Include:

  • Evaluating potential trademark infringement involving online product listings.
  • Advising on available Amazon Brand Registry and marketplace reporting procedures.
  • Reviewing possible takedown and infringement-reporting options across relevant platforms.
  • Preparing appropriate cease-and-desist communications.
  • Considering available legal remedies, including litigation when warranted.
Our Approach: We review the available evidence, assess potential trademark claims, and help clients understand appropriate enforcement options. Marketplace actions and legal outcomes depend on the facts, applicable laws, and platform procedures.

TTAB Proceedings & Trademark Opposition Defense

Trademark applications and registrations may become the subject of opposition or cancellation proceedings before the Trademark Trial and Appeal Board (TTAB).

Our attorneys assist clients with evaluating and addressing trademark disputes involving TTAB proceedings.

TTAB Services May Include:

  • Evaluating trademark opposition claims and available defenses.
  • Representing applicants in opposition proceedings.
  • Assessing potential cancellation actions involving existing trademark registrations.
  • Reviewing evidence and developing case strategies.
  • Advising on procedural requirements and potential resolutions.
What to Expect: TTAB proceedings address registration-related trademark disputes through an administrative process. The available options, expenses, and potential outcomes depend on the individual matter.

International Trademark Protection via Madrid Protocol

Businesses expanding internationally may need to consider trademark protection in countries where they plan to operate or sell their products.

Our attorneys advise on international trademark protection strategies, including potential use of the Madrid Protocol.

International Trademark Services May Include:

  • Reviewing international trademark protection needs.
  • Discussing available Madrid Protocol filing options.
  • Identifying relevant jurisdictions for possible trademark protection.
  • Advising on international filing procedures and applicable requirements.
  • Coordinating filing strategies based on the client's business objectives.
Important Consideration: The Madrid Protocol may provide a streamlined process for requesting trademark protection in multiple participating jurisdictions. Protection is not automatic. Each designated jurisdiction applies its own examination requirements and applicable fees.

Why Chicago Businesses Face Trademark Risks

Trademark disputes can arise when businesses select a brand name, begin using a mark, or file a federal trademark application. Understanding these risks early can help businesses make informed decisions.

Without Federal Trademark Registration, Your Protection May Be Extremely Weak

Using a trademark in commerce can establish common-law trademark rights even without federal registration. However, those rights may have a more limited geographic scope, and establishing or enforcing them can be more complicated.

Important considerations:

  • Common-law trademark rights may arise from actual commercial use of a mark.
  • The scope of unregistered rights may depend on when and where the mark has been used.
  • A competitor's later trademark filing does not automatically eliminate valid earlier trademark rights.
  • Federal registration provides additional legal protections and advantages, subject to applicable limitations.
  • A comprehensive trademark search may help identify potential conflicts before filing or expanding a brand.

The key takeaway: Federal registration is not required for every trademark right to exist, but it can provide important advantages for businesses seeking broader protection.

Conflicting Trademark Filings Can Disrupt Your Business

A trademark dispute can arise when two businesses claim rights in similar marks used for related goods or services.

A conflicting application or an allegation of earlier trademark use may require legal review, additional evidence, negotiations, or formal proceedings.

Potential Business Impact:

  • Costs associated with changing a business name, logo, or branding materials.
  • Possible loss of brand recognition or disruption to existing marketing.
  • Additional legal expenses associated with resolving trademark disputes.
  • Delays in product launches, brand expansion, or registration plans.

Reduce Potential Risk: Consider a trademark search and legal review before making substantial branding investments. Early planning can help identify concerns, although it cannot eliminate every potential dispute.

DIY Trademark Filing Can Lead to Additional Costs and Delays

Businesses may choose to prepare and submit their own federal trademark applications. However, errors or unresolved legal issues can lead to additional work, expense, or a refusal of registration.

Common USPTO Issues Include:

  • Likelihood of confusion with existing trademarks.
  • Merely descriptive or otherwise unregistrable marks.
  • Inadequate or improper specimens of trademark use.
  • Incorrect identification of goods or services.
  • Missing information or other application deficiencies.

Potential Additional Expenses:

Depending on the circumstances, applicants may incur additional USPTO fees, legal fees for responding to Office Actions, or the costs of submitting a new application.

Practical Approach: A trademark attorney can help review potential risks, explain filing requirements, and prepare an application. Legal assistance does not guarantee that the USPTO will approve a trademark.

Brand Protection Planning

Trademark Protection Checklist

If any of the following situations apply to your business, a trademark review may help you understand potential risks and available protection options.

  • Your brand name or logo is not federally registered.
  • You have not conducted a trademark search to identify possible conflicts.
  • Your business operates across multiple states or sells products through online marketplaces.
  • You are concerned about another business using a similar brand name or logo.
  • You are preparing to launch a new product, service, or business brand.

Understand Your Trademark Options

Our attorneys can review your circumstances and explain available trademark registration and protection strategies.

Federal registration is not required for all trademark rights to exist. Trademark protection depends on the facts, applicable law, and nature of the mark.

Schedule Your Service Consultation

"Let's discuss your trademark concerns, review your circumstances, and explore the legal options available to protect your brand."

From Initial Trademark Consultation to Legal Protection & Enforcement

Our attorneys help businesses understand trademark registration, potential conflicts, and available enforcement options. The process depends on each client's circumstances, the agreed scope of representation, and applicable legal requirements.

STEP 1

Initial Consultation & Trademark Search Options

Contact our office at (630) 318-2606 to discuss your brand, business objectives, and potential trademark concerns. Our attorneys can review your circumstances and explain whether a trademark search or clearance analysis may be appropriate. Comprehensive trademark searches, including relevant USPTO and other records, can be arranged as a separately scoped service. A written clearance report may be provided when included in the agreed engagement.

Consultation: Initial Review
Search: Separately Quoted
Report: As Agreed
Important: A trademark search is not automatically included in the standard application filing fee. Availability and registrability cannot be guaranteed through a search alone.
STEP 2

Federal Trademark Application Preparation & Filing

When engaged for federal trademark registration, our attorneys prepare and submit the application materials to the United States Patent and Trademark Office. This may include reviewing the identification of goods or services, application requirements, and relevant filing information. The USPTO independently examines each application and may issue an Office Action identifying legal or procedural concerns. If an Office Action is issued, we can discuss the available response options and applicable additional legal fees.

Application: Agreed Filing Fee
USPTO Fees: Additional
Office Actions: Separately Scoped
Examination: Timeline Varies
Registration Disclaimer: USPTO approval is not guaranteed. Examination timelines, additional requirements, and outcomes depend on the application and applicable trademark law.
STEP 3

Trademark Protection & Infringement Response

Trademark rights may require ongoing attention as a business expands, introduces new products, or encounters potentially conflicting marks. Where separately arranged, monitoring services may help identify potential trademark concerns. If infringement or another trademark dispute arises, our attorneys can review the available information and discuss possible legal responses. Depending on the circumstances, these may include cease-and-desist communications, negotiations, marketplace reporting procedures, or TTAB proceedings.

Monitoring: If Separately Engaged
Dispute Review: Case Specific
Options: Negotiation / TTAB
Service Scope: Ongoing monitoring and enforcement services are not automatically included with a trademark application. Any additional representation depends on a separate agreement or the existing engagement terms.
STEP 4

Federal Trademark Litigation When Appropriate

Some trademark disputes may require consideration of federal court proceedings. Our attorneys evaluate relevant facts, trademark rights, available evidence, and potential legal remedies when advising clients about litigation. Sherinian Law has historical experience with federal trademark disputes in the Northern District of Illinois, including past multi-defendant Schedule A litigation matters. The firm no longer offers that particular Schedule A litigation format. Current litigation matters are considered individually based on their legal and practical circumstances.

Litigation: Case-by-Case Assessment
Fees & Timeline: Matter Specific
Schedule A: Historical Experience
Important: Federal litigation is not a necessary or appropriate step for every trademark matter. No particular court result, financial recovery, or resolution timeframe can be guaranteed.

These steps describe potential trademark legal services and do not represent a mandatory sequence for every client. The scope of representation, fees, and available legal remedies depend on the engagement and individual circumstances. Past results do not guarantee similar outcomes in future matters.

Chicago Trademark Guidance · Common Risks

4 Common Trademark Mistakes Chicago Businesses Make

Trademark problems can begin during branding, searching, and filing. These four issues are worth reviewing before making major decisions about a business name or logo.

Trademark Guidance · Case File Mistake 1 of 4
#1 Brand without a search

Building a Brand Without Checking for Conflicts

A business may invest in a name, website, packaging, or advertising before checking whether someone else has earlier trademark rights in a similar mark.

Why It Matters

An existing federal registration or earlier unregistered use may create a conflict. Resolving it could involve negotiations, changes to branding, or legal proceedings.

Practical Step

Consider a trademark search and legal review before making substantial branding investments. A search can help identify risks but cannot guarantee that a proposed mark is available or will be registered.

Trademark search, application filing, and Office Action responses may involve separately agreed legal and government fees. No filing or search can guarantee registration.

Frequently Asked Questions: Trademark Attorney Chicago

Yes. Without an attorney, you risk USPTO rejection for issues like likelihood of confusion or improper specimens. We handle the entire process—from comprehensive searches to office action responses—so your application gets approved the first time instead of starting over.

The reality: 50% of DIY filers face rejection. Attorney-assisted filings have 83%+ approval rates.
Technically, yes. But DIY applications are the #3 reason clients come to us after their USPTO rejection. Common issues: likelihood of confusion, descriptive terms, improper specimens. Most DIY filers eventually hire an attorney—but after paying twice (refile fees + attorney fees). Start right. Hire an attorney upfront for flat-fee protection.
USPTO fees are $350–$550 per class. Our flat-fee attorney services cover search, application prep, and filing—no hourly billing surprises.

Cost comparison: Hourly attorney ($600+/hour) = unlimited costs. Our flat fee ($1,500–$3,000) = predictable investment. Hiring an attorney upfront costs LESS than fixing a DIY rejection later.
Often Yes. You may hear that filing a trademark is not necessary for protection, but without federal trademark registration, it can be very difficult to win a case against someone that has a federally registered mark. One of our most common cases is where a late-coming competitor registered the long-time brand of a client that came to us. This is a problem that can cost tens or even hundreds of thousands of dollars to fix.

Even worse: Competitors can file before you and legally own YOUR brand nationwide—even if you were first to market. Federal registration = legal ownership + enforcement power.
No. Trademark attorneys handle brand names, logos, and slogans under the Lanham Act. Patent attorneys handle technical innovations and mechanical devices. Different expertise. Different laws. Different processes.

We have deep expertise in trademark law—that's where our expertise is deepest and our results speak for themselves loudest (50+ Schedule A victories).
Trademark law is part of intellectual property (IP) law. It's governed by the Lanham Act at the federal level. Trademark registration happens at the USPTO. Enforcement happens in federal court (like our 50+ Schedule A cases in the Northern District of Illinois). We're federal IP litigation experts specializing in trademark enforcement.
Trademark lawyers are called "trademark attorneys," "IP attorneys," or "trademark lawyers"—the terms are interchangeable. What matters is specialization. General attorneys handle many practice areas. We specialize in trademark law. This specialization is why we win 50+ federal court cases—because this is what we do every single day.
