Wilmington, Del – Inventors and Patents

Wilmington’s history is rich with innovation. By 1868, Wilmington produced more iron ships than the nation as a whole, and was the nation’s second largest producer of leather, gunpowder, and carriages. With its post-war prosperity, residents were able to build elaborate new homes and expand the City to the west.


Wilmington has a long history of innovation and invention, and its residents are known worldwide for their contributions to business and industry. In addition to producing well-known products such as Gore-Tex, Kevlar, Tyvek, and Nylon, the city is also home to some of the world’s most famous patents and trademarks.

Wilmington’s history traces its origins back over 350 years. The town was first settled by Swedish colonists, who later became part of the British. During the Industrial Revolution, the city saw a great deal of development, including the completion of the Philadelphia, Wilmington & Baltimore Railroad. The completion of this railroad made Wilmington an accessible city by rail, road, and water, and connected it to the main north-south transportation route. The city’s strategic location allowed it to develop into a prosperous residential and business hub.

Many early African American inventors secured patents for their work. The first practical typesetting machine was developed in 1875 by Fenton Foster. In 1888, John C. Steel invented a lightweight hand-operated brick truck, which helped him establish a successful brick-producing company. Other notable Wilmington-area inventors include Carl R. Livermon, who patented an improved peanut picker and patented it in 1912. The city is also home to several other patented inventions, such as the central air-cooling device and a folding wheelbarrow.

Inventors from Wilmington have contributed to numerous inventions, from simple tools to life-saving products. Some of them are simple, like the Glider Skirt, which prevents fingers from being caught in popular chairs. Other inventions include the Drink Genie, invented by Wilmington’s Pete Vinyl. After knocking too many drinks on the beach, he developed the invention to keep drinks out of his way. Unlike many other devices, the Drink Genie is easily attachable to virtually anything.


The City of Wilmington has filed for and received patents on several inventions. For instance, in the past week alone, three Delaware patents have been granted. One of them is for a composite washer. Another patent is for an improved half bushel for measuring. Three other Wilmington residents were also granted patents: William I. Emery, a Wilmington resident, and John C. Rupp. These companies, along with others, have made a number of innovations.

Other inventions that have received a Delaware patent are those by Jes. Pyle, a Wilmington, Del. resident, who received a patent on an improved shaft coupling. Another invention came from Middletown resident, Adam Reed, who received a patent for a horse collar fastener.

Wilmington is also the home of the first horsecar line in the country. The city is a leader in the production of iron ships, gunpowder, carriages, and leather. The post-World War II prosperity brought a new vigor to Wilmington. Multiple redevelopment projects and a Back to the Cities movement have sparked an economic boom.

Patent litigation in Delaware has been a popular venue for a century. With the recent TC Heartland decision, more patent cases have moved into the First State. With a larger pool of cases, Wilmington-based IP litigators have responded. In addition to helping businesses protect their inventions, the Wilmington office has made significant contributions to the Wilmington community through volunteerism, fundraisers, and other efforts.


In the USPTO database, inventors and assignees are listed, with their address information. The patent office also lists citations between patents. This information is useful for determining who invented what. You can also find assignees’ addresses, including PO Boxes.

Assignees of inventors and companies are grouped based on their geographic location. Assignees in one city will be listed together, but inventors may be in multiple cities. Inventors can also move from one city to another, so they may be in different countries.


The Delaware Patent Office has published a list of inventions and patents issued by Delaware citizens. The latest list was published the week of July 24, 1874. There were three patents granted to Delaware residents in the previous week. One of them was to a composite washer. Another was to a jump seat. These inventions were developed in Wilmington, Del.
