Mark S. Hamill

For individuals and entities in Chicago seeking legal counsel, the "Nearby Lawyers" platform serves as a resource for connecting with various legal professionals. Among the attorneys whose name may appear is Mark S. Hamill. His address is provided as 300 North LaSalle Blvd, Ogilvie/Union, IL - Lasalle/Clark, IL, Chicago, IL 60654, USA. It is important to note that public records from the Illinois Attorney Registration and Disciplinary Commission (ARDC) and the United States Patent and Trademark Office (USPTO) indicate a complex history regarding Mark S. Hamill's legal practice. This introduction will objectively detail his reported environment, the services he has been associated with, features as a legal professional, and relevant promotional information, based strictly on the available information.

The address provided, 300 North LaSalle Blvd, Chicago, IL 60654, is a significant professional building in Chicago's downtown area. This location is typically associated with prominent law firms and corporate offices, suggesting a high-caliber professional environment. However, specific details about Mark S. Hamill's current or past direct affiliation with a particular firm at this exact suite number are not readily available in public records alongside the disciplinary information. While such a location would normally imply a well-maintained, professional, and accessible office, designed to facilitate client meetings and legal work, the context of the disciplinary actions requires a careful interpretation of this environment. It is a known address for various legal entities and provides general access for anyone in the Chicago metropolitan area. The prestige of the building itself, therefore, reflects more on the general legal landscape of the area than on the specific nature of Mark S. Hamill's practice within it, given the documented professional issues.

Based on publicly available information, Mark S. Hamill was licensed to practice law in Illinois on November 7, 1991, and was registered as a patent attorney with the United States Patent and Trademark Office (USPTO) on October 8, 1993. Therefore, the primary legal services he has been associated with fall under intellectual property law, specifically patent and trademark law. This would typically involve:

• Patent Prosecution: Assisting clients with the application process for obtaining patents for their inventions.
• Trademark Registration: Guiding clients through the process of registering trademarks to protect their brands and logos.
• General Intellectual Property Advice: Providing counsel on various aspects of intellectual property rights, including protection, enforcement, and licensing.

However, it is crucial to present the context of his professional conduct as reported by the ARDC. Records indicate that on December 4, 2019, Mark S. Hamill was excluded from the practice of patent, trademark, and non-patent law before the USPTO for engaging in misconduct. This exclusion is for a period of at least five years, contingent upon establishing full compliance with specific regulatory conditions for reinstatement. Furthermore, the Illinois ARDC records indicate a three-year suspension and until further order of the Court, until he pays restitution, stemming from disciplinary proceedings initiated in 2021. The complaints included failing to act with reasonable diligence and promptness in representing a client (specifically by failing to respond to notices from the USPTO), failing to keep a client reasonably informed about the status of their matter, and falsely informing a client that an application was still pending when it had been abandoned. This indicates that while his expertise was in intellectual property, his ability to provide those services effectively and ethically became compromised.

The features of Mark S. Hamill, as derived from the public records, present a mixed picture.

• Initial Licensing and Registration: He was a licensed attorney in Illinois since 1991 and a registered patent attorney since 1993, which initially signified a level of legal qualification and specialized expertise in intellectual property.
• Past Professional Recognition: Older records or affiliations might list him as a partner at a firm like Kirkland & Ellis LLP or Baker McKenzie, suggesting a period of recognized professional standing. For instance, a 2007 press release indicates he was appointed as a new partner at Kirkland & Ellis LLP in their litigation practice. This highlights a background in complex litigation, possibly including intellectual property disputes.
• Disciplinary Actions: A significant feature, however, is the documented disciplinary history. The USPTO excluded him for misconduct, and the Illinois ARDC ordered a suspension and restitution due to his failures in client communication and diligence, including providing false information to a client and failing to respond to official notices. These actions are serious and directly impact his ability to practice law.
• Lack of Client Communication and Diligence: The ARDC's findings specifically highlight a failure to act with reasonable diligence and promptness, as well as a failure to keep clients reasonably informed. These are fundamental ethical and professional responsibilities for an attorney.
• Exclusion from Practice: The exclusion from USPTO practice means he cannot represent clients in patent, trademark, or non-patent matters before that office. The Illinois suspension similarly limits his ability to practice law in the state.

These features, particularly the disciplinary actions, are critical for any potential user of the "Nearby Lawyers" platform to understand when considering Mark S. Hamill's profile.

In terms of promotional information, the provided contact details are phone (312) 861-2000 and mobile phone +1 312-861-2000. His address is 300 North LaSalle Blvd, Ogilvie/Union, IL - Lasalle/Clark, IL, Chicago, IL 60654, USA. However, given the public disciplinary records, any objective introduction must integrate this information. While a "Nearby Lawyers" platform typically promotes an attorney's availability and expertise, in this case, the most significant promotional caveat is the public record of his suspension and exclusion from practice. Potential clients seeking legal services should be aware of these official disciplinary actions. His eligibility for reinstatement before the USPTO is contingent upon a five-year period from December 4, 2019, and full compliance with conditions, while the Illinois suspension is "until further order of the Court and until he pays restitution." This means his current ability to provide legal services is severely restricted or entirely suspended in Illinois and before the USPTO. Therefore, promotional information for Mark S. Hamill, based on an objective internet search, would need to clearly state that while he has a background in patent and trademark law, his current capacity to practice is limited by disciplinary actions from both state and federal regulatory bodies. Any engagement would require careful verification of his current standing with the ARDC and USPTO. Direct contact via the provided phone numbers would be necessary for any potential client to ascertain his current licensure and ability to provide legal services.
