Maryland MD mostly utilizes patented and proprietary products for certification and synchronization in state and local municipality projects . In addition, Eric Dougherty is responsible for processing and approving the Patent and Proprietary Products for certification and synchronization for the State of MD. This includes the local municipalities as well.
Minnesota Each product has its own process to obtain approval.
Mississippi As part of our project development process, proprietary products are identified during a project's office review meeting and then the appropriate division submits a form to FHWA for approval so that the product can be called out in the project plans. The MDOT Construction Division will maintain an internal list of approved proprietary products as they are introduced and used on new projects. To my knowledge, there is no procedure whereby a manufacturer can get a product approved and added to the list.

New Mexico View
New York NY does not maintain any listing of proprietary products. We will draft special specifications for products we need in certain circumstances and typically cite performance characteristics of the materials w/o using any specific trade names. Once in awhile we will cite trade names but always include 3 equivalent products and state "or approved equal" in a special specification. Once we have established availability and/or use of a specification citing 3 or more items we often create a Section 700 Material requirement and an approved list category… which then means the item isn't proprietary. The exception to the 3 name spec situation is when we are evaluating a product for experimental reasons and then FHWA typically requires us to consider the material as an Experimental Features and perform specific evaluations and reporting. We make very few requests to use proprietary items because the FHWA NY Division will not approve the use of proprietary materials in general. New Product Evaluation Application

North Dakota NDDOT doesn't maintain a list of acceptable products, proprietary or otherwise, that are acceptable under our specifications.We accept products either thru a testing program (if one exists for that particular item) or via Certificate of Compliance from the contractor/manufacturer stating that the material meets the appropriate requirements under the contract. This summarized on our website under a heading normally associated with a QPL or APL

Wyoming WYDOT avoids using proprietary products. We are working on establishing a qualified product list (QPL) however it's not designed to approve proprietary products that can be used on state projects. Instead, it will be used to circumvent/supplement the process of submitting material certifications at the project level.
