When is Your Trademark Being Infringed?

As an owner of a registered trademark or service, you probably wonder when others are responsible for infringing your mark. You should know that the test for trademark infringement is the likelihood of confusion as a result of the similarity of the marks.
What is Likelihood of Confusion for Trademark Infringement?
A person may be liable for infringement of a federally registered mark if his use of a mark in relation to any goods of services is likely to cause confusion, mistake or to deceive. 15 U.S.C.A. § 1114(1). This test to determine whether a registered mark is being infringed is known as the test of likelihood of confusion.
Likelihood of Confusion as to Source, Affiliation, Connection or Sponsorship
The test of likelihood of confusion includes not only the confusion as to source but also as to affiliation, connection or sponsorship. Champions Golf Club v. Champions Golf Club, 78 F.3d 1111, 1121 (6th Cir. 1996) (internal citations omitted). This means that a user of a mark may be liable for trademark infringement if the use creates a likelihood of confusion that the goods are affiliated to, connected with or sponsored by the owner of the registered mark.
Likelihood of Confusion Means Probability of Confusion
In order to show likelihood of confusion, there must be a probability of confusion; mere possibility of confusion is not enough. Nora Beverages, Inc. v. The Perrier Group of America, Inc., 269 F.3d 114, 121 (2d Cir. 2001) (internal citations omitted). It should also be noted that plaintiff does not have to prove actual confusion in order to show that the defendant is liable for trademark infringement. Perfumebay.com Inc. v. eBay, Inc., 506 F.3d 1165, 1176 (9th Cir. 2007) (internal citations omitted). If the plaintiff is able to show likelihood of confusion the defendant will still be liable for trademark infringement even if the plaintiff shows no instances of actual confusion.
There Should Be a Likelihood of Confusion of an Appreciable Number of Reasonably Prudent Consumers
The test for likelihood of confusion is whether a reasonably prudent consumer is likely to be confused as a result of the similarity of the marks. Dreamwerks Production Group, Inc. v. SKG Studio, 142 F.3d 1127, 1129 (9th Cir. 1998) (internal citations omitted). The likelihood of confusion exists when there is a likelihood that an appreciable number of reasonably prudent consumers is likely to be misled or confused because of the similarity of the marks. McGregor-Doniger, Inc. v. Drizzle, Inc., 599 F.2d 1126, 1130 (2d Cir. 1979) (internal citations omitted). To sum up, there is a likelihood of confusion when there is a probability that an appreciable number of reasonably prudent consumers will be confused as to the source, affiliation, connection or sponsorship of goods or services because of the similarity of the two marks.
What Factors Determine if There is a Likelihood of Confusion?
The Sleekcraft Test for Likelihood of Confusion
Federal courts in different federal circuits have come up with multi-factor tests in order to determine whether there is a likelihood of confusion or not. The test in the 9th Circuit, which includes the State of California, is the eight-factor Sleekcraft test pursuant to which the court shall consider the following factors to determine if there is a likelihood of confusion or not:
- strength of the mark;
- proximity of the goods;
- similarity of the marks;
- evidence of actual confusion;
- marketing channels used;
- type of goods and the degree of care likely to be exercised by the purchaser;
- defendant’s intent in selecting the mark; and
- likelihood of expansion of the product lines.” AMF, Inc. v. Sleekcraft Boats, 599 F.2d 341, 348-49 (9th Cir. 1979) (internal citations omitted).
These factors are not requirements but are helpful guidelines for courts in order to determine whether there is a likelihood of confusion or not. Eclipse Ass’n, Ltd. v. Data General Corp., 894 F.2d 1114, 1118 (9th Cir. 1990). The application of the text shall be flexible, and there is no specific formula setting forth how the factors included in the text shall be considered. Nautilus Group, Inc. v. ICON Health and Fitness, Inc., 372 F.3d 1330, 1346 (Fed. Cir. 2004) (internal citations omitted). The important question is what the analysis as a whole reveals about the issue of likelihood of confusion. Entrepreneur Media, Inc. v. Smith, 279 F.3d 1135, 1141 (9th Cir. 2002). This means that none of the factors is determinative but the analysis as a whole shall answer the question whether there is a likelihood of confusion or not.
The Degree of Similarity of Marks Necessary to Prove Likelihood of Confusion Varies Depending on the Similarity of Goods or Services
It should be noted that the degree of similarity of marks necessary to show likelihood of confusion varies depending on the competitiveness of goods and services. The more similar the goods or services the less similar marks need to be in order to prove likelihood of confusion. Century 21 Real Estate Corp. v. Century Life of America, 970 F.2d 874, 877 (internal citations omitted). Conversely, “… the greater the degree of similarity between the marks, the lesser the degree of similarity between the goods is necessary to support a finding of likelihood of confusion.” The Board of Regents, University of Texas System v. Southern Illinois Miners, LLC, 110 U.S.P.Q.2d 1182, 1189 (internal citations omitted). Hence, if the marks are very similar the court may find a likelihood of confusion even if the goods or services at issue are not very similar. To summarize, your trademark or service mark is being infringed if a use of another mark creates a likelihood of confusion among consumers. If the other mark is very similar to your trademark or service mark you might have a cause of action for trademark infringement even if the goods or services are not very similar. If you believe someone is infringing on your trademark or have questions regarding trademark registration, copyright, or any other intellectual property related question, we invite you to contact our office and speak to one of our experienced business attorneys at (310) 943-1171.

E-bikes are gaining popularity across California, offering an efficient and eco-friendly way to get around. But with the rise in usage, the number of e-bike injury incidents involving both riders and pedestrians has also grown. If you’ve been injured while riding an e-bike—or struck by one—you need to take swift action to protect your health and your legal rights. Here's what to do immediately after an injury accident in California
Step 1: Get Medical Attention for Your E-Bike Injury
Your health should always come first. After an e-bike injury, call 911 or go to the nearest emergency room, even if you feel okay. Some injuries, such as concussions or internal bleeding, may not show immediate symptoms.
Seeing a doctor promptly not only protects your health but also creates a medical record that can be critical if you decide to pursue a legal claim.
Step 2: Report the E-Bike Injury to the Police
Call local law enforcement to report the accident. In California, any collision involving injury or property damage must be documented. The responding officer will create an official police report.
Be clear and honest when giving your statement. Make sure you ask how to obtain a copy of the report. It will serve as important evidence in your case.
Step 3: Preserve Evidence—Don’t Disturb the Scene
In any e-bike injury case, preserving the accident scene is critical. If you are physically able, avoid moving the e-bike, other vehicles, or debris until authorities arrive. This helps investigators document the scene accurately.
Take photographs or videos of:
- Damaged e-bikes or vehicles
- Skid marks and debris
- Traffic signs or signals
- Visible injuries
- Your location relative to the road or sidewalk
If you're unable to take photos yourself, ask a witness or bystander to help. Never clean up or move items until the scene is documented.
Step 4: Collect Witness Statements After an E-Bike Injury
Witnesses can play a key role in verifying your version of events. If anyone saw the crash, ask them for:
- Full name
- Contact information
- A brief statement of what they saw
Eyewitness accounts are especially helpful in e-bike injury cases involving disputes over right of way, sidewalk use, or rider negligence.
Step 5: Document Your Injuries and Financial Losses
Keep records of everything related to your e-bike injury, including:
- Photos of injuries
- Doctor’s notes
- Prescriptions
- Physical therapy sessions
- Time missed from work
- Property damage (e.g., broken phones, cracked helmets, damaged e-bike)
Hold on to all bills, receipts, and repair estimates. This documentation will help build your case and support your claim for compensation.
Step 6: Don’t Speak to Insurers Without Legal Help
After an e-bike injury, insurance companies may contact you for a statement. Don’t provide one without first consulting a lawyer. Insurers often try to minimize payouts or shift blame.
At KAASS LAW, we deal with insurance adjusters on your behalf. We make sure your rights are protected and help you pursue fair compensation.
Step 7: Understand Liability in an E-Bike Injury Case
Determining fault is key in any e-bike injury case. Liability may fall on:
- A negligent e-bike rider
- A driver who hit a rider
- The city has hazardous road conditions
- An e-bike manufacturer is experiencing equipment failure
A personal injury attorney can help investigate the cause, gather evidence, and identify all responsible parties.
Common Causes of E-Bike Injury in California
Here are the common causes of e-bike injury for both riders and pedestrians:
- Reckless or speeding riders
- Riding on sidewalks or pedestrian paths
- Distracted riding or driving
- Mechanical failures (brakes, tires, batteries)
- Dooring accidents from parked vehicles
- Failure to yield at crosswalks or stop signs
If negligence was involved, you may be eligible for compensation for your injuries and damages.

What Are California's Clean Car Rules?
Clean Car rules refer to California's vehicle emission standards aimed at reducing air pollution and greenhouse gases. These rules come from the California Air Resources Board (CARB). They require automakers to cut tailpipe emissions and produce zero-emission vehicles like electric or hydrogen-powered cars.
California's program is stricter than federal rules. Over a dozen other states have adopted these standards under Section 177 of the Clean Air Act.
Legal Challenge to Clean Car Standards Gains Traction
Recently, the U.S. Supreme Court allowed a lawsuit against California’s Clean Car rules to move forward. This case was brought by Republican-led states and industry groups. They claim that California's authority to set its own emission rules is unconstitutional.
The main argument revolves around the federal Clean Air Act. It allows California to request a waiver to impose stricter standards. The plaintiffs argue that these waivers create confusion and impose unfair burdens on car manufacturers. Automakers must then meet both federal and California standards.
Supreme Court Declines to Block the Case
The Supreme Court did not rule on the lawsuit’s outcome. Instead, it simply allowed the case to continue in lower courts. This reverses earlier decisions that blocked the case on jurisdictional grounds.
California Attorney General Rob Bonta has promised to defend the rules. Environmental groups also support the Clean Car program, citing public health and climate benefits.
What This Means for Automakers and Consumers
If the challenge succeeds, California might lose its power to enforce stricter emissions rules. Automakers would likely reduce investments in zero-emission vehicles for the California market.
Consumers could see fewer Clean Car options and increased vehicle emissions. If California wins, the state could continue shaping national clean vehicle policy and technology.
Environmental and Health Impacts
Clean Car standards are about more than climate change. They address serious public health concerns. Vehicle emissions worsen smog and trigger asthma and heart conditions, especially in cities.
California suffers from some of the worst air pollution in the U.S. Areas like Los Angeles and the Central Valley are most affected. Clean Car rules aim to reduce the harm caused by millions of vehicles.

Legal Battle Over State vs. Federal Power
This lawsuit raises big questions about federalism. Should California be able to set stricter rules than the federal government?
The Clean Air Act gives California the right to apply for waivers. That’s because the state has struggled with air pollution for decades.
Opponents argue these waivers give California too much control over national markets. Supporters say they drive innovation and protect public health.
The Trump administration revoked California’s waiver. President Biden later restored it. The back-and-forth has led to legal uncertainty.
Clean Car Standards Drive the Electric Vehicle Future
No matter how this case ends, the shift toward electric vehicles (EVs) is underway. Automakers like Tesla, Ford, and GM are heavily investing in EVs.
Clean Car rules helped build charging infrastructure and encouraged EV adoption. Weakening these rules might slow progress. But market forces and climate goals will likely keep the EV transition moving forward.

Conclusion
The Supreme Court’s action allows a high-stakes lawsuit against California’s Clean Car rules to move forward. The outcome will affect state powers, public health, and the auto industry.

California positioned itself as a leader in reproductive rights by passing legislation that would expand IVF access through mandated insurance coverage. However, a recent amendment to the law has delayed its implementation from 2025 to 2026. This decision has left many prospective parents feeling abandoned, financially overwhelmed, and unsure of their next steps.
At KAASS LAW, we help individuals and couples navigate the complex legal and insurance systems tied to fertility treatments. In this post, we examine what California’s delayed IVF law means and what options remain available for those affected.
IVF Access Law: What California Promised
The law aimed to increase IVF access by requiring most health insurance plans in California to cover in vitro fertilization. Governor Gavin Newsom signed the law in October 2023, with the original start date set for January 1, 2025.
Specifically, the law:
- Defined infertility as a disease
- Required insurance providers to cover diagnosis and treatment, including IVF
- Applied to both employer-sponsored and individual health plans
By removing cost barriers, the state hoped to give more people the chance to build families through assisted reproductive technologies. However, legislators have now pushed the effective date to January 1, 2026.
IVF Access Delay: Real-World Consequences
This delay affects more than just policy—it impacts lives. IVF success rates often depend on timing. A one-year wait can lower success rates, especially for individuals over 35 or those with medical conditions.
Here’s what the delay means for patients:
- Insurance companies are not legally required to provide IVF coverage until 2026
- Individuals must continue paying out-of-pocket or rely on plans that offer voluntary benefits
- Delayed access may force some patients to postpone or abandon fertility plans entirely
People now face added stress, high treatment costs, and fewer alternatives. While the law’s delay may serve administrative needs, it introduces serious emotional and financial challenges for families.
If you’ve been denied fertility-related benefits or misled by your insurer, KAASS LAW can help you understand your rights. Visit our insurance claim disputes page for support.
Why Lawmakers Delayed IVF Access
California lawmakers claimed that insurers and state regulators needed more time to implement the IVF mandate. Insurance companies argued that they required time to update policies, calculate cost impacts, and train staff.
Supporters of the delay believe that a smoother rollout will ultimately help everyone. But many reproductive health advocates disagree. They argue that the delay prioritizes bureaucracy over people who have waited long enough.
Fertility treatment is not a luxury—it is a medical necessity for thousands. Lawmakers must balance administrative readiness with real human needs.

Understanding the Legal Landscape of Reproductive Rights
California typically leads the way in protecting reproductive rights. While states like Alabama and Tennessee restrict IVF and other treatments, California’s legislation represents progress. However, delays like this reveal gaps between legal promises and practical realities.
Patients still lack guaranteed access to IVF, even though the law exists. Until full implementation occurs, patients must rely on employer benefits, personal savings, or outside funding sources.
At KAASS LAW, we support clients facing legal and insurance hurdles related to healthcare. If your insurance policy misrepresents its fertility benefits or denies a valid claim, we’re ready to act. Explore our healthcare law services for more information.
What You Can Do While Waiting for Coverage
Even though the law won’t take effect until 2026, there are still actions you can take right now to protect your family-building journey:
1. Check your current coverage
Review your plan’s benefits and exclusions. Some employer-sponsored plans may offer IVF coverage voluntarily.
2. Ask your HR department or broker
Employers can modify group health plans at any time. If you’re part of a large organization, collective requests for fertility coverage may influence change.
3. Apply for fertility grants
Several nonprofits provide financial assistance for IVF. Clinics may also offer payment plans, refunds for unsuccessful cycles, or package pricing.
4. Document insurance interactions
Save emails, letters, and notes from calls with insurance reps. If your benefits are misrepresented or claims are wrongly denied, legal action may be possible.
5. Contact a fertility law attorney
You don’t need to navigate this alone. Attorneys experienced in insurance and healthcare law, like the team at KAASS LAW, can evaluate your situation and suggest the best next steps.
KAASS LAW Supports IVF Patients and Families
Fertility issues can be deeply personal and legally complex. The delayed IVF access law adds another layer of difficulty to an already overwhelming process. Our attorneys work with clients to resolve disputes involving:
- Denied insurance claims for IVF or other reproductive procedures
- Failure to disclose policy limits or exclusions
- Misleading marketing materials related to fertility coverage
- Delays or denials based on age, gender, or medical history
We take a proactive approach to insurance disputes. Whether you need help appealing a denial or filing a legal complaint, KAASS LAW stands by your side throughout the process.
IVF Access Can’t Wait
Delaying IVF access might serve short-term policy goals, but it harms real people today. Fertility doesn’t pause for bureaucratic processes, and neither should your ability to receive care. California made a bold promise by passing this law. Now, the state must ensure its timely and effective implementation.
In the meantime, patients deserve accurate information, strong legal protections, and affordable options. At KAASS LAW, we are committed to helping families overcome the legal and financial barriers that stand between them and their dreams of parenthood.
