What Is A Patent Print? Unravel The Captivating Narrative Behind Patent Prints

If you are a fan of crime shows or mystery novels, you have probably heard of fingerprints and how they can be used to identify suspects and victims.

But did you know that there are different types of fingerprints and that each one has its own characteristics and challenges?

In this article, I will explain what a patent print is, how it differs from other types of fingerprints, and why it is important for forensic science.

What Is a Patent Print?

A patent print is a visible image of a person’s fingertip left on a surface as a result of residue on the finger.

A patent print can be created by blood on someone’s finger, another liquid such as oil or ink, or by dirt.

Unlike latent prints, which are invisible to the naked eye and require special techniques to be revealed, patent prints are easily seen and can be photographed without any processing.

How Does a Patent Print Differ from Other Types of Fingerprints?

There are three main types of fingerprints that can be found at a crime scene or on an object: patent prints, latent prints, and plastic prints. Each type has its own advantages and disadvantages for forensic analysis.

  • Latent prints are made of the sweat and oil on the skin’s surface and are transferred by the friction of touch. They are not readily visible and need to be made visible with powders, chemicals, or light sources. Latent prints are the most common type of fingerprints and can be found on almost any surface. However, they are also the most fragile and can be easily damaged or destroyed by environmental factors or human interference.
  • Plastic prints are three-dimensional impressions of a person’s finger left in a pliable substance, such as clay, wax, or wet paint. They are also visible and can be photographed as they are. Plastic prints are rare and usually only found in cases where the perpetrator or the victim touched a soft or sticky material. They are also more difficult to compare with other prints because they may be distorted or incomplete.
  • Patent prints are visible images of a person’s finger left on a surface as a result of residue on the finger. They are also visible and can be photographed as they are. Patent prints are less common than latent prints but more common than plastic prints. They are usually found on smooth or glossy surfaces, such as glass, metal, or paper. They are also more durable and less affected by environmental factors or human interference.

Why Is a Patent Print Important for Forensic Science?

A patent print is important for forensic science because it can provide valuable information about the identity and activities of a person involved in a crime. A patent print can:

  • Confirm or exclude a person as a suspect or a victim. By comparing a patent print with a known fingerprint, such as an exemplar print taken from a person or a database, forensic experts can determine if the print belongs to that person or not. This can help narrow down the list of potential suspects or identify a victim.
  • Link a person to a crime scene or a weapon. By finding a patent print on a surface or an object that is relevant to the crime, such as a door handle, a knife, or a note, forensic experts can establish a connection between a person and the crime scene or the weapon. This can help reconstruct the sequence of events or the motive of the crime.
  • Provide clues about the time and manner of the crime. By analyzing the type and amount of residue on a patent print, forensic experts can estimate when and how the print was made. For example, a patent print made by blood may indicate that the person was injured or bleeding, a patent print made by ink may indicate that the person was writing or signing something, and a patent print made by dirt may indicate that the person was outdoors or in a dirty environment.

Conclusion

A patent print is a visible image of a person’s fingertip left on a surface as a result of residue on the finger.

It is one of the three types of fingerprints that can be found at a crime scene or on an object, along with latent prints and plastic prints.

A patent print is important for forensic science because it can provide valuable information about the identity and activities of a person involved in a crime.

By using patent prints, forensic experts can solve crimes and bring justice to the victims and the perpetrators.
