6 Must-Haves for Every Fourth of July Celebration: Patents, Trademarks, and the Spirit of Independence

Since 1941, the Fourth of July has been recognized as a federal holiday in the United States—but the celebration of American independence dates back much further. On July 2, 1776, the Continental Congress voted in favor of breaking ties with Great Britain. Just two days later, the newly drafted Declaration of Independence—penned by Thomas Jefferson—was adopted, giving birth to the nation we know today.

From 1776 to today, Americans have marked the Fourth with fireworks, parades, patriotic music, and backyard barbecues. But beyond the festivities lies a fascinating layer of legal protection—through trademarks, copyrights, and patents—that supports many of our favorite July 4th traditions. Here are six iconic must-haves that combine celebration with creativity and legal ingenuity.

1. The American Flag: A Symbol of Freedom

The U.S. flag is the most recognizable symbol of American patriotism. While an authentic version of the flag cannot be trademarked or patented, stylized or modified designs can be protected under intellectual property law. For example, if a flag is heavily integrated into a logo or altered from the traditional form, it may qualify for trademark registration.

Even the display of the flag has inspired innovation. One notable invention is a flagpole design by Robert Ellis, patented in 1945 (US Patent No. 2530654 A). This design helped raise those broad stripes and bright stars higher than ever before — perfect for backyard displays or civic events.

2. “The Star-Spangled Banner”: America’s Anthem in the Public Domain

One song you’re guaranteed to hear at a July 4th event is “The Star-Spangled Banner.” Written by Francis Scott Key in 1814 during the War of 1812, the lyrics—combined with a British tune—eventually became the national anthem.

Because the anthem was published well before 1923, it resides in the public domain—free for all to sing, perform, and record without paying royalties. So, belt it out proudly during your celebration; it belongs to everyone.

3. Fireworks: Lighting Up the Sky and the Patent Office

No Fourth of July is complete without fireworks lighting up the night sky. Behind the spectacle lies a long history of pyrotechnic innovation. Among the many patents filed over the years is one for a Launcher for Launching Multiple Fireworks Projectiles (US Patent No. 5282455 A), granted in 1994.

This clever invention allows for multiple fireworks to be launched in succession, creating the dazzling, layered displays we associate with major Independence Day celebrations. Without inventions like these, we’d be stuck watching one firework at a time—not quite the same grand finale.

4. Backyard Barbecues: The Grill Master’s Patent Playground

Grilling is practically a national sport on July 4th, and inventors have fueled this culinary tradition with creativity. A prime example is the Barbecue Grill and Smoker (US Patent No. 20110120442 A1), which combines features of gas grills and wood smokers.

Designed to be user-friendly for the home cook, this hybrid invention delivers mouth-watering flavors while minimizing the need for culinary skill. Whether you prefer ribs, hot dogs, or veggie skewers, this innovation keeps the party sizzling.

5. Popsicles: A Patent Born from a Happy Accident

Looking to cool off on a hot July afternoon? Thanks to 11-year-old Frank Epperson, who accidentally invented the popsicle in 1905 after leaving a sugary drink with a stirring stick outside on a freezing night. His discovery eventually led to US Patent No. 1505592 A, granted in 1924.

Today, the term “Popsicle” is a registered trademark owned by Unilever (which also owns Creamsicle, Fudgsicle, and Yosicle). In fact, the company even protects the suffix “-sicle” as part of its “SICLE™ Trademark Family.” That means only they can sell flavored frozen treats on a stick using that name, though many others make similar icy delights.

6. Beer: Raise a Glass to America’s Oldest Brewery

Whether you’re at a barbecue, beach, or rooftop celebration, chances are someone’s reaching for a cold beer. And what better brew to toast the USA than one with nearly two centuries of American heritage?

Yuengling, founded in 1829, holds the distinction of being America’s oldest operating brewery. Its registered trademark—YUENGLING TRADITIONAL LAGER SINCE 1829 BY AMERICA'S OLDEST BREWERY—pays homage to both its history and national pride. Cheers to that.

From inventions and anthems to tasty treats and timeless symbols, the Fourth of July is a celebration of both America’s past and its creative spirit. Patents, trademarks, and copyrights may seem far removed from summer fun, but they play a vital role in shaping the experiences we cherish.

So, this year, while you're enjoying grilled favorites, waving flags, watching fireworks, or cooling off with a popsicle, take a moment to appreciate not just our independence—but the ingenuity that helps bring it to life each summer.

Happy Fourth of July!
