My project-4

Intellectual Property, Business and On-Demand General Counsel Services for Startups, Entrepreneurs, and Businesses

Contacting a lawyer can be intimidating. On the other hand, putting one off can be downright painful.

The journey of an idea or a business is a long road that can take some unexpected twist, turns, and uphill climbs. Your initial route might have to morph over time and having a team of resources to turn to can help you with the best navigation.

The right business structure, contracts and agreements, and intellectual property protections can fortify your business and your place in the market as well as put your mind at ease on what the road looks like moving forward. My mission is to take the intimidation out of speaking with a lawyer and give you the confidence and peace of mind with a good short term plan plus a healthy long term strategy.

Areas of Practice

Patent Prosecution aka Patent Applications

Patent prosecution is the filing of patent applications and correspondence with the Patent office with the goal of achieving an issued patent. There are different types of patent applications as well and seeking advice from a registered patent attorney before beginning the process can help save time and valuable resources.


Business names, logos, and brands can make your business stand out from the rest. Protecting that name and ensuring that no one else out there is using it can make a huge difference in your business's success.


Copyrights are a type of IP protection that apply to creative works such as music, lyrics, artwork, written works, photographs etc. A copyright registration can protect your work from unauthorized use by another.

Speaking Engagements and Workshops

A focus of Black Dog Law is educating people on the various types of intellectual property protections and what they can mean for your business.

Contract Drafting

Business relationships can be a huge help for all parties involved. But sometimes, these relationships don't always go as planned. A written understanding of the business relationship protects both parties involved and can be critical to protecting your IP, your business, and your peace of mind.

Infringement Opinions

"Cease-and-Desist" Letters, Notices, and Demand Letters are typically what are sent out if someone believes another to be infringing upon another's intellectual property. Having an attorney review the facts and claims can help you determine what action needs to be taken, put your mind at ease, or protect your assets.

Outside Counsel

Businesses face potential legal issues almost every day. Having an attorney you can call on when you need them can be incredibly helpful for navigating situations that could morph into disaster.

Startup guidance and consulting

Starting and building a business has many stages. Different type of contracts and agreements are needed along the way and can ensure that founders and investors are protected every step of the way.
