Oh, patents! LeafFilter®

Copyright © Francoise Herrmann

Guaranteed for life, LeafFilter® offers “gutter protection perfection”! Indeed Leaf Filter® is the largest gutter protection company in the United States. They have installed 269,592,100 feet of LeafFilter® gutter protection (and counting) to 1,797,250 customers, with zero clogged gutters. 

Difficult to clean and dangerous to access for cleaning, clogged gutters also cause roof and siding damage, basement flooding, and even foundation damage. Compared to existing gutter protection systems: hood, foam, screen and brush, LeafFilters® are installed on a pitch, on existing gutters, with no gaps, large holes or openings. Comprising a patented three-piece system (micromesh to screen even shingle grit, a temperature-resistant unplasticized polyvinyl [uPV] frame, and hangers inside the gutter to secure the filter), LeafFilters® cause debris to simply roll off, and only water to collect inside gutters. Debris that includes dirt, leaves, pine needles, even grit and seed pods,

The following are a few of the LeafFilter® utility patents, covering various aspects of the LeafFilter® gutter protection system: 

• US10633868B2 - Main bodies with securing features for use with modular platform for gutter guard systems with interchangeable components. 
• US10655334B2 - Adjustable width gutter guard systems. 
• US11078670B2 - Systems and methods for modular platform for gutter guard systems with interchangeable components.
• US11591800B2 - Gutter assessment and method. 

The below patent Figure 1 is extracted from one of the design patents, USD885533S1, titled Gutter guard assembly. This patent was awarded on May 26, 2020, to the LeafFilter®  inventors, Michael Gori, Michael J. Peck,  and Scott M. Garbe. The patent was then assigned to LeafFilter North, LLC. The patent Figure 1 shows a perspective view of the gutter guard system.  An image of the installed, marketed, and pitched LeafFilter® is also included below. Specifically, the image shows the micromesh on top of the uPV frame, installed on a pitch, on a gutter.

Oh, patents! The Rolodex®

 Copyright © Françoise Herrmann

Does anyone still use a Rolodex®? Hard to believe that the Rolodex® is almost 70 years old! The trademark Rolodex® is a portmanteau term combining “rolling” and “index”. Invented in 1958, the Rolodex® is an office supply device meant to organize index-card contacts on a cylinder that rotates. The term “rolodex” has certainly endured since people refer to their “rolodex” even when it is an electronic version. In any event, non-electronic Rolodex® organizers are still available on the market.

The Rolodex® is a patented invention. A French patent, FR1197557A, titled Fichier rotatif, was filed on July 3rd, 1958 and awarded the following year, on June 1st, 1959, to Arnold Neustadter, residing in the United States. He was the founder of Rolodex, Inc., a company manufacturing Rolodexes®, as well as many other sorts of office supplies.

Interestingly, the French patent also specifies that an earlier US patent had been filed in the United States, by Mr Hildaur Lykee Neilsen, on March 25th, 1958. An annotation that is consistent with claims by Hildaur Neilsen’s daughter, who specifies that Arnold Neustadter was the entrepreneur who manufactured and marketed patented products, whereas her father, Hildaur Neilsen, was the commissioned inventor and licensor for many years at Rolodex Inc., without ever being an employee on record (Hall, 2014).

The French patent recites an index-card organizing device where it is far easier to consult and annotate information, because the index cards are not positioned directly horizontal, relative to the user (as they might be in a tray), but rather at an angle. Thus, the invention seeks to resolve the issue of easy access to card contact-information, rotating through the stack, both forward or backward, while able to set card position at an optimal angle for consultation and annotation. The invention also seeks to minimize wear of the rotating drum.

The patent Figure 1, depicting a perspective view of the device, is included below, together with the image of a vintage Rolodex®. Specifically, the patent Figure 1 depicts a tubular metal support, comprising two opposite and similar sides connected by a transverse element 10, each side of the support further comprising a base piece 12 and an upright 14. The uprights 14, on each side of the support, rise at the same angle, and are attached at their upper end with openings for supporting pins, provided on each side of a rotor formed by a drum 20. On at least one of the pins, or to each of them, a handwheel 22 is fixed. One or two handwheels 22,  which can be operated by a user of the device to rotate the cards 26. Some of the cards 26 have tabs 30, indexed with letters of the alphabet, or numbers, to facilitate the task of locating and annotating a particular card 26.

EPO Young European Inventors Awards – The 2025 Trophy

Copyright © Françoise Herrmann

The winners of the Young European Inventors Awards not only receive cash prizes. The winners also receive a trophy. A trophy masterminded by Miriam Irle, an industrial designer located in Munich, Germany. The trophy is truly special on several counts. First, the shape of the trophy is symbolic. Crafted as a “sail” (no pun intended), the trophy was designed as a symbol of the exploration and ingenuity that propels inventors on the frontiers of discovery. Secondly, the trophy is fabricated each year from locally significant materials, in the city or country where the Awards ceremony is held. Thus, for example, in 2016, when the European Inventor Awards were held in Lisbon, Portugal, the sail trophies were each uniquely crafted from Portuguese azulejo ceramics. Likewise, in 2017, when the European Inventor Awards were held in Venice, Italy, the sail trophies were each uniquely crafted out of the famous Murano glass.

The year 2025 was no exception. To celebrate the winning Young European Inventors, each team received a uniquely designed sail trophy, crafted from black sand and glass, by Brynhildur Þorgeirsdóttir, a renowned artist in Reykjavik, Iceland. Black sand resulting from the erosion of volcanic rock, found on the beaches at Reynisfjara, on the south coast of Iceland. And glass, reminiscent of the glacial landscape in Iceland, where a thriving community of glassmakers exists.

Below, the image of a black sand and glass model for the sail trophies that were presented on June 18th, during the Awards Ceremony, held in Reykjavik, Iceland. According to Miriam Irle (personal communication forwarded to her):

"The trophies were produced by a local glass artist (https://www.brynhildur.com/about). Color was slowly dropped into the hot glass to achieve the melted structure. After being polished, a double layer of black volcanic sand was added, and the letters were sandblasted (the trophy in the photo was the backup, hence no labeling). The trophies were color-matched to the four categories and were produced in blue, black, red, and yellow."

Juneteenth 2025!

 Copyright © Françoise Herrmann

Juneteenth, a portmanteau term for “June Nineteenth”, celebrates Black emancipation from slavery. Specifically, Juneteenth celebrates June 19th, 1865, when military General Orders #3 were given by Major-General Granger to proclaim the emancipation of slaves in Galveston, Texas, one of the last outposts of slavery. Orders given to implement Abraham Lincoln’s Proclamation of Emancipation, dated January 1st, 1863. Orders, in fact given just a few months prior to ratification of the 13th Amendment to the United States Constitution, on December 6th, 1865, formally abolishing slavery across the US.

 

However, the Juneteenth National Independence Day Act was only signed into law on June 17th, 2021, by then-President Joe Biden. At the end of the day, recognition of Juneteenth as a National federal holiday, marking Black Independence Day, rights a wrong. A wrong, because on Independence Day, July 4th, 1776, the United States declared independence from Great Britain, while Black Americans remained in bondage.

Oh, patents! Land Life's Cocoon (video)

Copyright Françoise Herrmann

Land Life is participating in the World Economic Forum challenge to plant one trillion trees. One trillion trees to combat climate change and the dramatic deforestation that has occurred in the past 25 years. Indeed, trees are one of the most effective ways of capturing carbon dioxide (CO2), the primary source of greenhouse gases, which is assumed to be responsible for climate change. Trees capture more CO2 than any other existing plant. 

The video below shows how Land Life seedlings are planted in their (patented) Cocoons.

Oh, patents! Land Life’s Cocoon

Copyright © Françoise Herrmann

The Dutch company, Land Life, invented the Cocoon, a sustainable way of planting trees in degraded and harsh environments. Harsh environments where soils are arid, temperatures are extreme, and pests are abundant. Degraded lands where the earth no longer supports biodiversity and productivity, resulting in desertification due to a combination of natural causes, such as drought, and human activity, such as deforestation, unsustainable agricultural and husbandry practices, or urbanization.  

According to Land Life, two billion hectares of land (the size of the surface of China and the United States combined) are deemed degraded. Thus, the company's mission is to sustainably reforest 100 million hectares of degraded land. Reforestation will not only restore ecosystems, but most importantly serve to sink carbon dioxide (Co2), a greenhouse gas that contributes to global warming. The company’s Cocoon is 95%  effective at shielding young seedlings from extreme temperatures, and at keeping a moist environment for the seedling, even in a host desert environment, without the need for added water, for up to a year after planting. 

The Cocoon, an evolving, donut-shaped protection for seedlings is a patented invention, recited in several utility patents. In particular, the US patent, US103083291B2, titled Method and apparatus for planting in arid environments, recites the donut-shaped invention, and method of using the invention for sustainably planting seedlings. The patent was awarded to Jurriaan Hendrik Ruys and Eduard Willem Zanen from the Netherlands, and to Steven Caffall Finch from the United Kingdom on September 15th, 2016.  

The donut-shaped invention comprises one or several water reservoirs, depending on the aridity of the soil, each with a moisture-resistant cover, and a wick acting as a slow irrigation channel between the water reservoir and the soil beneath. At the center of the reservoir, a perforated shroud is inserted upright to shade and protect the seedling. The reservoir, its cover, and the perforated shroud are each made of biodegradable pulp, with waterproofing additives to retain moisture. The wick is made of a strip of capillary matting material such as nylon or polylactic acid (PLA) with a width that is selected according to the desired flow rate. The reservoir and cover are buried in an excavated hole, flush with the ground surface both to mechanically support the reservoir walls and to protect them from animal attack and harsh temperatures. Once the reservoir is positioned in the excavated hole, the seedling in a plug of growing medium is inserted into the perforated shroud at the center of the reservoir. Then, the reservoir is filled with water and covered. 

Thus, the reservoir, together with its cover and the shroud extending above ground, create a protective microclimate for the seedling, while slowly decomposing and eventually leaving no trace, as the seedling matures, grows roots, and establishes itself. A process that also requires initial installation training, as well as preliminary satellite survey and soil analysis. Required preliminaries to determine the choice of seedling and to devise a growing plan, considering that different soils react in different ways.

The patent Figure 15B below shows a cross-sectional view of the Cocoon apparatus. The reservoirs 40 are filled with water 54, and protected from evaporation with a lid 42. At the center of the reservoirs 40,  the shroud 20,  extends up above the ground surface 51, while the lower portion 22, of the shroud 20, is buried in the soil 53. At the bottom of the shroud 22, the seedling’s upper portion 4 protrudes from the upper portion 6 of the plug 2, comprising growing medium 5.  The wicks 43 are shown at the soil level 53 surrounding the reservoirs 40. The bottom of the plug body 10 is shown in contact with the soil 53, where roots will eventually grow. 

The image on the left shows the Land Life Cocoon with a seedling at the center of the donut -shaped reservoir, being filled with water. The image on the right shows the closed buried reservoir, now protected from evaporation and rodents, with a shrouded and growing seedling, at the center.

Below, the abstract of the invention.

An apparatus for planting a seedling (3) in an arid area comprises a vertical, downwardly tapering shroud (20) and a seedling plug (1) comprising a body of growing medium covered by a moisture-resistant cap (14) which preferably is sealingly received in a lower region (22) of the shroud. The lower region of the shroud surrounding the upper portion of the seedling is buried beneath ground level (51) with at least one water reservoir (40, 200) and supplied with water via capillary wicks (43), the reservoir being buried beneath ground level and covered by a moisture resistant cover (60) which sealingly surrounds the shroud. The shroud extends above ground level to protect and shade the seedling and together with the cap (14) and cover (60) serves to retain moisture in the planting region for the first year of growth.

Oh, patents! Oscillum smart food safety labels

Copyright © Françoise Herrmann

Three young European inventors, founders of the Oscillum Biotechnology company, make some important points about the unreliability of  “sell by”, “best by” and expiration dates. Unreliability relative to the shelf life and quality of perishable products, such as food, cosmetics, and medicines. The inventors point out that a food product, for example, might still be in good condition past the indicated "sell by", "best by" or expiration dates, which are generally conservative estimates. And, just as important, they point out that a food product might no longer be in good condition prior to the dates specified, simply because the product might not have been stored in the required manner (e.g., the product might have thawed and then re-frozen), or because the product might have been contaminated during transportation. 

The inventors further explain how both scenarios are problematic. In the first scenario, when products are still in good condition past the expiration, "best by" or "sell by" dates, this results in large amounts of waste. Waste that the United Nations Food and Agriculture Organization (FAO) estimates at 1/3 of the global food production, 60% of which is wasted at the household level. Waste, which has been quantified, for food, in billions of Euros on the Oscillum Biotechnology company website. The second scenario is a public health risk. Perishable products that go bad undetected, or are contaminated, at any time prior to the indicated "sell by", "best by" or expiration dates, whether food, cosmetics, or medicines, may create serious health emergencies. 

In the absence of reliable ways to prevent such seriously problematic situations, concerning the shelf life of perishable products, such as food, and by extension cosmetics and pharmaceutical products, the inventors have designed smart labels. Smart labels, stand alone or embeded in films and packaging, placed on a product, or around it, that reliably detect physical, chemical and biological changes in a perishable product. The smart labels contain sensors that react to various stimuli. Stimuli such as chemical or biological molecules within or released by the products, and environmental changes such as temperature, which would affect product stability, over time. 

This smart label invention is recited in the Spanish patent ES1309897U, titled (in translation to English) Indicator label that allows to detect and alert the state of decomposition of a food*. The patent was awarded on Aug. 19, 2024, to Pilar Granado, Pablo Sosa Domínguez and Luis Chimeno, in Spain.  

The patent Figure 1 below depicts the gradual color change that occurs on the inventive smart label, included on a product support. The patent describes the components comprising the smart label matrix that function to detect food decomposition through chemical, biological and physical, or environmental changes. The direct sensing of changes, occurring relative to internal food composition and its interaction with external factors, provides a better and more reliable real-time indicator of perishable food decomposition. An image of the marketed product is also included below the patent figure. The image shows changes in the smart label color across time for a piece of salmon. 

A non-legally binding Google translation of the patent abstract is included below.

Indicator label that allows detecting and alerting the state of decomposition of a food through physical changes, chemical or biological changes, or through environmental changes, which is characterized because it comprises a matrix in combination with additives; and at least one agent that produces the change and acts as a sensor. [Abstract ES1309897U]

Evie!

Copyright © Françoise Herrmann

On May 20th, 2025—amidst re-escalating tensions in the Middle East, the fragile onset of the Ukraine-Russia peace negotiations, and in the aftermath of Pope Francis’s death—the popular press and broadcasting networks were proud to announce the birth of Evie*…! Evie?

Peppa Pig’s baby sister! A breath of fresh air, and very popular British children’s cartoon character, Peppa Pig is four years old. She lives with Mummy Pig, Daddy Pig and her little brother George, in Peppatown, in the United Kingdom.

Just shy of two weeks before the Peppa Pig meets the Baby motion picture release (on May 30th), Evie promises to add to the multi-billion dollar Peppa Pig industry for the five-and-under crowd. A multibillion-dollar industry that includes theme parks and a television channel, in addition to all the licensing and merchandising of the cute little pig and her family.

Newsworthy indeed, Peppa Pig has had her fair share of surprising controversies, since 2004 when she was first aired in the UK. In May 2018, for example, she made headlines when she and her whole family, including the hashtag #PeppaPig, were censored in China (Qin, 2028). Assumed slovenly, the bossy big sis piggy and her familly ran counter to the desired cultivation of young generations.

Then again, she made headlines during the pandemic when she became the second most-watched children’s television cartoon in the US after SpongeBob SquarePants, surpassing audience demand in the UK by 112% (Yang, 2021). Popularity that was feared to result in giving American children a posh British accent. A Peppa effect that was causing American children to start calling their Moms “Mummy” instead of Mommy, and “biscuits” instead of “cookies”.

Finally, most recently in 2024, Peppa Pig was accused of making American children “rude” (Leiber, 2024). Picking up on Peppa’s reactions, parents heard their kids say “Yuck” when served new (surely unpalatable) foods. A “no, no” indeed among parents who see Peppa as brash, too direct and berating  her father when she chides him about his big belly. A bit of a backlash, according to the Wall Street Journal, for all the self-assertiveness, self-confidence and authenticity that the multinational Hasbro conglomerate professes in response. 

Luckily for this blog, Peppa Pig is also a US registered Trademark and logo, with Evie sure to follow. The included Peppa Pig US Trademark was filed on July 9th, 2005, and granted on Sept 23, 2008 to HASBRO, and then renewed. Below, an image of the US registered Trademark No. 3506452  and of the cartoon logo.
