Today the US Patent & Trademark Office published a series of six patent applications from Apple titled "Electronic Device," that relate to various aspects of the Apple Watch Ultra.

The patent background for all six patents are common stating that "electronic devices are increasingly being designed with device portability in mind, for example, to allow users to use these devices in a wide variety of situations and environments. In the context of wearable devices, these devices can be designed to include many different functionalities and to be operated in many different locations and environments. The components of an electronic device, for example, the processors, memory, antennas, display, and other components can partially determine a level of performance of the electronic device. Further, the arrangement of these components with respect to one another in the device can also determine the level of overall performance of the electronic device.

Continued advances in electronic devices and their components have enabled considerable increases in performance. Existing components and structures for electronic devices can, however, limit the levels of performance of such devices. For example, while some components can achieve high levels of performance in some situations, the inclusion of multiple components in devices sized to enhance portability can limit the performance of the components, and thus, the performance of the device. Consequently, further tailoring and arrangement of components for electronic devices to provide additional or enhanced functionality, without introducing or increasing undesirable device properties, can be desirable."

Apple's patent FIGS. 2A and 2B illustrates that the patent is about the Apple Watch Ultra; FIG. 8 shows a method of bonding a metal substrate to a non-metal substrate.

After some time comparing patents, it became clear that 90% of each of them are identical. It appears that Apple legal apparently wanted to distinguish the patents by their patent claims alone. This makes it impossible to neatly summarize.

For those that are technically curious as to what Apple desires to protect in each of the Apple Watch Ultra patents, I've created a list of the first patent claim of each of the six patents below so you could see for yourself what the differences are per patent.  

To dive even deeper, I've provided links to each patent. At the bottom of every patent that you click on are 20 specific and different patent claims that you could review for additional Apple Watch Ultra details.

Patent 20230229205 

An electronic device, comprising: an outer housing defining an internal volume; a first speaker and a second speaker disposed in the internal volume, the first speaker including a frame disposed around a periphery of a diaphragm of the first speaker; a front volume defined by the outer housing, the first speaker, and the second speaker; a first back volume defined by the first speaker and the frame; and a second back volume defined by the second speaker and the frame.

Patent 20230229197

An electronic device, comprising: a housing defining an internal volume and an aperture; a button disposed in the aperture, the button including a plunger extending into the internal volume; and a speaker frame disposed in the internal volume and defining an opening; wherein the plunger extends through the opening

Patent 20230232151 

A wearable electronic watch, comprising: a housing having a sidewall, the sidewall defining: an internal volume, the sidewall extending 360-degrees circumferentially around the internal volume; a first aperture; a second aperture between about 155 and 205 degrees relative to the first aperture; and a third aperture closer to the second aperture than the first aperture; and a first microphone disposed in the internal volume and configured to receive sound through the first aperture; a second microphone disposed in the internal volume and configured to receive sound through the second aperture; and a third microphone disposed in the internal volume and configured to receive sound through the third aperture.

Patent 20230232560

An electronic device, comprising: a housing sidewall defining an opening; a display component disposed in the opening and defining a gap between the housing and the display component; a cavity defined by the sidewall and the display component, the cavity in fluid communication with an external environment through the gap; and an epoxy at least partially defining the cavity and in direct contact with the housing sidewall. 

Patent 20230232547

An electronic device, comprising: a sidewall including an antenna, the sidewall defining an internal volume; a printed circuit board (PCB) disposed in the internal volume; an insulating material disposed in the internal volume; and an electrical connector contacting the PCB, the electrical connector extending through the insulating material and forming an electrical contact between the antenna and the PCB.

Patent 20230225619 

An electronic device, comprising: a housing defining an internal volume, a front opening, and a rear opening; a display component disposed at the front opening; a rear cover disposed at the rear opening; a first temperature sensor disposed adjacent to the display component; and a second temperature sensor disposed adjacent to the rear cover; and a processor electrically connected to the first temperature sensor and the second temperature sensor, the processor configured to determine a core temperature of a user based on a first temperature detected by the first temperature sensor and a second temperature detected by the second temperature sensor.
